Taking It Mobile: Why a Coatings Trailer Fits the RV Roof Business
RVs are big, and their owners don't love driving them across town for service. A Mobile Coatings Unit puts your whole shop where the RVs already are.

Most service businesses ask customers to come to them. With RVs, that’s a harder ask. They’re big, they’re often parked for the season, and plenty of owners would rather not drive a 35-foot motorhome across town. A mobile setup flips the model: you bring the shop to the roof.
What a Mobile Coatings Unit is
ArmorThane’s mobile spray rigs are enclosed trailers with the spray system built in. The standard build is a 20′ rig with a PMC PHX-40 proportioner, a 45 kW generator, a 23 CFM air compressor and 100 feet of hose; 24′ and 26′ gooseneck rigs are also available. Instead of installing equipment in a building, the proportioner, heated hose, power and storage for material and supplies live in the trailer. Hook it to a truck and your workshop goes wherever the work is.
Why mobile works so well for RV roofs
- RVs cluster. Campgrounds, RV parks, storage facilities and dealer lots put dozens of roofs in one place. One location can mean several jobs.
- No shop lease to start. You can begin without a building and decide later whether a fixed location makes sense.
- Easier yes for customers. “We’ll come to you” removes one of the biggest hurdles in the sale.
- Professional first impression. A clean, branded rig parked beside the RV says you’re a real business.

Building a route instead of waiting for calls
The smartest mobile applicators don’t just respond to calls; they build relationships with places where RVs live. A campground or storage facility manager who knows you can do roofs on site becomes a steady referral source. A dealership with trade-ins that need roof work becomes a repeat account.
Weather and planning
Spraying outdoors means paying attention to conditions. The ArmorThane method depends on a clean, dry surface — moisture left on the roof is a leading cause of blisters. Mobile applicators plan around the forecast, start with prep, and have the flexibility to move a job a day when they need to.
Mobile today, fixed location tomorrow
Some applicators stay mobile for good. Others use a trailer to build a customer base, then add a shop. ArmorThane notes that qualifying fixed-location dealers can receive a protected territory at no added cost — one more reason to grow into a building once the demand is there.
