If you manage an RV lot, you've probably gotten washing quotes that ranged so widely they were useless — because half the vendors were pricing a residential job 200 times. Commercial inventory washing is a different product with different math. Here's how the pricing actually works, so you can compare proposals like an operator.
Per-unit pricing is the only honest model
Hourly pricing punishes you for the vendor's inefficiency; flat lot pricing hides what you're paying for. A real program quotes per unit, by class — a 40-foot Class A is not a travel trailer — so your invoice scales exactly with your inventory and you can audit it against your unit count in thirty seconds.
The five factors that set your per-unit rate
- Unit count: volume is leverage. Crews that wash 200 units in rows price each unit far below a 20-unit visit, because setup and travel amortize across the count.
- Unit mix: Class A and fifth-wheel units carry more surface, more height and more roofline than towables; programs price classes separately.
- Frequency: biweekly units never get truly dirty, so they wash faster — standing programs price below one-time cleans per unit, sometimes dramatically.
- Site water access: lots with accessible water hookups wash cheaper than sites where the vendor hauls water. Know your answer before the walkthrough.
- Event work: show support prices differently — tighter timelines, travel, and off-hours passes — usually as a per-event package on top of the base program.
What should be IN the price
Black-streak and road-film removal, bug zones, decal-safe soft-wash chemistry, washing units in place without key shuffling, front-line prioritization, and documentation. If a low per-unit quote excludes the streaks and bugs — the two things your customers actually see — it's not a lower price, it's a smaller product.
How to run the comparison
Give every vendor the same brief: unit count by class, desired frequency, water access, and event calendar. Demand per-unit pricing in writing. Then weight reliability over rate — a program that actually shows up every other Tuesday is worth more than a cheaper one you have to chase. Ask what happens when it rains, who's insured, and how decals are protected; the answers separate programs from pressure washers fast.
