ou’ve just finished a 1,200-mile road trip in your Class A motorhome. The rig is covered in road grime, bug splatter, diesel soot, and a generous layer of highway residue from three different states. You pull into the nearest car wash, and — surprise — you don’t fit.
This is one of the most frustrating realities for RV owners: the wash infrastructure built for passenger vehicles simply wasn’t designed for them. And for businesses that serve the RV market, that gap represents a significant missed opportunity.
The Size Problem Is Real
The average Class A motorhome stretches 30 to 45 feet long and stands over 12 feet tall. Standard in-bay automatic car wash equipment typically accommodates vehicles up to 7 or 8 feet high — barely enough for a full-size pickup truck. The mechanical arches, brushes, and spray systems on a conventional car wash don’t travel far enough to cover the height or length of an RV without leaving large sections unwashed or, worse, causing equipment damage.
The result? RV owners are largely left on their own — either hand-washing an enormous vehicle (a multi-hour ordeal), finding a self-serve bay with enough clearance and hoping the wand reaches the roof, or driving miles out of their way to one of the rare facilities with proper large vehicle equipment.
The Contamination Challenge
Beyond size, RVs present a different kind of contamination load than cars. Extended highway driving means heavy accumulation of dead insects, road salt, diesel exhaust film, and oxidized surface coating. Motorhomes with fiberglass or painted exteriors are also more sensitive to certain cleaners and abrasive media than fleet trucks — so wash systems need to balance aggressive cleaning chemistry with surface protection.
Standard car wash detergent formulations and brush types aren’t calibrated for these materials. A wash designed for daily passenger vehicle traffic will under-clean an RV that’s been on the road for weeks.
Purpose-Built Equipment Changes Everything
The solution isn’t adapting a car wash — it’s deploying equipment built specifically for large vehicles from the ground up.
D&S Car Wash Systems manufactures the IQ MAX, an automated large vehicle wash system engineered for exactly this challenge. Unlike retrofitted passenger car equipment, the IQ MAX is purpose-built for the dimensions, throughput demands, and contamination loads of commercial trucks, buses, RVs, and heavy equipment. The system accommodates full-size motorhomes, fifth wheels on tow vehicles, and everything in between — without asking the driver to guess whether they’ll fit.
For RV parks, dealerships, and campgrounds looking to serve their guests at a higher level, having the right equipment isn’t a luxury. It’s the difference between turning a guest frustration into a genuine amenity.
