A Buyer's Guide to Towability: What to Know Before Buying a Manufactured Home

Stuck with an unmovable home? How to know if a manufactured home is truly towable before you buy

Buying a manufactured home can save tens of thousands of dollars — until you learn the unit isn’t towable without expensive repairs, permits, or a whole new plan. If your goal is mobility, resale flexibility, or simply a predictable move-in process, towability must be assessed before the contract is signed. This guide gives buyers a practical, 2026-ready playbook: chassis checks, coupling points, size classes, operator requirements, pre-move inspection steps, and safe DIY fixes you can do or expect your mover to require.

Top-line checklist: What determines towability (quick view)

1. Chassis condition — rust, cracks, axle integrity, bearings, springs.
2. Coupling points — hitch, anchor bolts, shear plates, safety chains.
3. Size class — singlewide, doublewide, widths/heights that trigger oversize permitting.
4. Operator requirements — permits, pilot cars, insurance, digital inspections.
5. Route restrictions — overpass height, bridge capacities, urban turning clearances.

The evolution of towability in 2026 — what’s changed and why it matters

Manufactured homes today are structurally more sophisticated than the “mobile homes” of decades past. By 2026, movers and DOTs have widely adopted digital tools and more stringent documentation: electronic oversize permits became common in many states in late 2024–2025, and GPS/AI route planning with real-time clearance data is now standard for professional movers. That means a unit's towability is assessed not just by raw dimensions, but by digital route feasibility, documented chassis condition, and whether coupling hardware meets modern safety standards.

Why modern inspections matter

Operators expect a pre-move file: dimension sheets, photos of the chassis and coupling points, HUD/serial tags, and a basic mechanical inspection. A unit that looks fine visually can still fail permits because of axle spacing or roof-mounted obstructions. Buyers who purposefully confirm these details avoid surprise price hikes and delayed moves.

Tip: Ask sellers for a digital pre-move pack (photos + measurements) before finalizing purchase. Movers will accept electronic reports in 2026 — it's now standard practice.

Size class and legal thresholds — measure twice, move once

Size drives everything: cost, permitting, escorts, scheduling windows, and route options.

• Singlewide: typically under 18 feet wide and transportable on a chassis without splitting. Easier to move, often permitted with standard oversize processes.
• Doublewide: usually 18–32 feet wide when assembled — moved in two sections; each section still may need oversize permits and escorts depending on width and length.
• Triplewide / modular sections: large sections that require heavy-haul permits, specialized dollies, and often temporary road closures or utility work.

Important thresholds (varies by state): many states set 8.5 feet as the normal legal width for no-oversize permit; widths over 10–12 feet generally require special permits and pilot cars. Height restrictions often trigger local overhead utility coordination (typical thresholds around 13'6"). Always confirm with the mover and state DOT for the exact limits on your planned route.

Chassis condition: the most critical structural check

The chassis is literally the backbone of towability. A compromised chassis turns a straightforward move into a heavy-haul project.

What to inspect

• Main rails and I-beam integrity — visible rust, section loss, deep pitting, or cracks at welds. Small surface rust is common; structural section loss is not.
• Cross-members — missing or broken cross-members reduce torsional strength.
• Axles and axle mountings — bent axles, out-of-line hangers, worn U‑bolts, or cracked spring mounts will fail a mover’s inspection.
• Bearings and hubs — dry or overheated bearings; signs of grease loss or metal dust around seals.
• Suspension — missing leaf springs, sagging suspension, or broken shackles.
• Floor-to-chassis connections — anchor bolts and shear plates where the living unit attaches to the frame. Loose or corroded anchors are red flags.

How to perform a fast chassis check (buyer-friendly)

1. Photograph both sides and all cross-members. Movers want close-ups of suspect areas.
2. Tap suspicious rusted areas with a screwdriver — heavy flaking or holes indicate section loss needing replacement.
3. Look for diagonal cracks at welds near coupling points and axle hangers.
4. Check tires for dry rot and hubs for grease stains (a sign of leaks).
5. Request recent axle/bearing service records; if none, budget for a bearing repack and axle inspection before moving.

Coupling points and attachment hardware — what movers will examine

Coupling points are the connection between the towing rig or dollies and the home/chassis. Problems here stop a move cold.

• Kingpin and hitch assemblies — for homes moved via gooseneck-style or specialized hitch gear; check for wear, shearing, and secure bolts.
• Anchor bolts and shear plates — confirm the home is firmly anchored to the frame. Loose anchor bolts are a fail for most operators.
• Safety chains and breakaway cables — present, rated, and in good condition.
• Electrical connections — functioning taillights, brakes, and auxiliary power connections; movers require operable lights for road moves. If the unit lacks functioning lights, operators will often accept plans to fit temporary tow lighting and auxiliary power sources.

What operators will require before accepting a move

• Clear photos of coupling points and detailed notes on any weld or bolt repairs.
• Evidence of functioning brakes and lights or plan to fit temporary tow lighting and electric brakes.
• Documentation of any recent chassis repairs and axle measurements.
• Signed disclaimers if the home remains on an old chassis that the operator considers marginal (expect surcharges).

Route restrictions and permitting — plan the path before you commit

Even a structurally perfect home can be unmovable if the route is restricted. Modern movers use AI-driven mapping, drone flyovers, and DOT electronic permit systems to pre-clear routes — a practice that grew exponentially in late 2024 and became standard across major carriers by 2025.

Key route checks

• Vertical clearances — bridges and utility lines. Measure roof height and add any transport fixtures.
• Bridge and road weight limits — especially important with doublewide/triplewide sections and long overhangs.
• Turning radii and street width — downtown moves often require temporary parking bans or lamp post removals.
• Utility coordination — schedule power/phone line drops or rewires if heights exceed limits.
• Time-of-day restrictions — many permits limit moves to nighttime or low-traffic windows.

What certified movers will ask for — prepare this before calling quotes

• Complete exterior dimensions (length, width, height).
• Chassis photos (both sides, underside cross-members, axles, coupling points).
• HUD label or serial number for code compliance history.
• Desired pickup/drop-off locations with GPS coordinates.
• Any on-site obstacles: trees, wells, fences, overhead wires.
• Desired move date and flexibility windows (important for permit timing).

Pre-move inspection checklist you can use on-site

1. Measure and photograph: overall length, width at widest points, height to peak, axle spacing, and wheelbase.
2. Walk the chassis: note rust, cracked welds, missing cross-members, bent hangers.
3. Test lights: tail, brake, and turn signals (or confirm operator will fit temporary lighting).
4. Check tires and hubs for dry rot or leaks; document tread depth and dated stamps.
5. Inspect coupling and anchor bolts; take close-up shots of fasteners.
6. Note interior attachments that increase height (antennas, rooftop units) and plan removal.
7. Confirm seller will disconnect utilities, remove skirting, and unbolt tie-downs before move day.

Practical, buyer-friendly DIY fixes and safe prep tasks

Some items buyers can handle or arrange cheaply before a mover arrives. These cost far less than emergency repairs billed at haul rates.

• Replace worn safety lighting — swap bulbs and wiring on exterior lights; a working lighting circuit can be the difference between “go” and “no-go.”
• Regrease wheel bearings — if you’re comfortable with basic hub work, repacking bearings and checking seals prevents in-transit failures. If unsure, hire a service technician.
• Tighten or replace U-bolts and shackles — common inexpensive repairs that restore axle security.
• Remove skirting and stabilizers — these must be removed prior to highway moves; do it ahead of time to save crews’ labor costs.
• Block and crib the unit — install proper cribbing at jacking points to stabilize during pre-move inspections.

Safety caveat: major structural repairs, axle or weld work, and any heavy lifting should be done by qualified technicians. Always use rated hardware and approved welding methods — a bad on-site weld can be catastrophic on the highway.

Vehicle recovery & winching basics for small incidents (what movers do)

Sometimes a unit must be winched off a pad or out of sticky ground before the highway move. Professional movers follow strict protocols; as a buyer you should understand these basics so you can spot cut corners.

• Use only rated recovery straps, shackles, and winches sized for the load. Never use chain unless rated and inspected.
• Stage snatch blocks to manage angle and reduce line load; keep angles shallow to avoid shock loading.
• Use cribbing and spread pads under jacks to avoid sinking into soft soil.
• Maintain two-way radios and a dedicated signal person to manage the pull — communication prevents errors.

If a mover proposes improvising with untested gear or using non-rated chains, stop the work and request certified equipment. That’s a legitimate red flag and a potential insurance issue.

Case Study A — Singlewide, rural move: low cost if you prep

Background: Buyer purchased a 14' wide singlewide on an aging chassis in a rural county. The mover required a digital pre-move pack and an axle/bearing check.

Action taken: The buyer hired a local mechanic to repack bearings, replace two cracked cross-members, and fit temporary tow lights. The mover used AI-based route planning to avoid a county bridge with a low load rating.

Outcome: Move completed in a single day with a standard oversize permit and no pilot cars — cost significantly lower than worst-case estimates because initial prep addressed the chassis issues.

Case Study B — Doublewide, suburban to urban: permits and coordination made the difference

Background: A 26' wide doublewide needed cross-town transport with low overhead wires and tight turns.

Action taken: The mover scheduled a nighttime move, coordinated utility line lifts, secured three pilot cars, and obtained a local road closure permit. The buyer removed rooftop HVAC units and documented all measurements in the pre-move file.

Outcome: The move required more upfront coordination and cost, but because the buyer provided complete documentation, the mover could book the specialized dollies and avoid on-site delays that would have doubled labor charges.

What to ask potential movers — a script for buyers

1. “Do you have experience with HUD-code manufactured homes and can you provide references?”
2. “What documentation do you need from me before you quote a firm price?”
3. “What permits and escorts will be required for my unit’s dimensions on this route?”
4. “What is your process for pre-move inspections and how is that recorded?”
5. “What insurance do you carry, and what is your liability limit for on-highway damage?”
6. “If a last-minute chassis issue appears, how do you handle repairs and how are they billed?”

Advanced strategies & 2026 predictions — what buyers should watch next

• Digital permitting becomes universal: by 2026 many state DOTs have integrated e-permits; expect faster approvals but stricter dimensional audits.
• Drone pre-inspections: more movers use aerial scans to confirm overhead clearances and create 3D site maps before quoting. See tools and workflows in the night-photographer toolkit used for aerial scouting.
• Adaptive transport gear: adjustable dollies and modular chassis adapters reduce the cost of moving larger sections — good news for buyers of multi-section homes. Related modular logistics are being discussed in the micro-events & pop-ups playbook.
• Liability scrutiny: tighter insurance checks mean movers will demand better pre-move documentation, shifting some prep costs to the buyer.
• Green moves: expect more carriers offering reduced-carbon routing or off-peak electric pilot vehicles, reflecting broader transport trends in 2025–2026. See sustainable building and operations thinking for homes at Sustainable Home Office in 2026.

Final practical takeaways before you sign

• Always get a pre-move pack: measurements, photos, HUD/serial tag, and a short chassis report will speed quotes and lower surprise charges.
• Inspect the chassis first: major frame or axle damage is a deal-breaker unless priced as a heavy-haul project.
• Know your size class: width and height determine permits, escorts, and route feasibility.
• Get mover requirements in writing: permits, insurance limits, and what they will charge for on-site repairs or delays.
• Budget for pre-move fixes: a few hundred to a few thousand dollars in chassis and lighting prep can save tens of thousands later.
