Single Axle vs. Tandem Axle Pressure Washing Trailers: How to Choose
Trailer size is one of the most consequential decisions you'll make when building out a pressure washing operation, because it determines how much water you carry, how long you can run before refilling, and how much weight and cost you're towing around.
Single Axle: Built for Agility
A single axle trailer, like the TideRite Single Axle system starting around $15,500, is compact and easy to maneuver into tight driveways and residential neighborhoods. It carries a smaller water tank, which keeps tow weight — and fuel costs — down. This is the right choice for owner-operators focused primarily on residential work: driveways, sidewalks, fences, and small commercial jobs where refilling every few stops isn't a major time cost.
Tandem Axle: Built for Volume
A tandem (double) axle trailer, like TideRite's setup starting around $18,900 and the most popular configuration among growing operators, adds a second axle for better weight distribution and stability, along with room for a larger tank. That translates directly into more billable hours per tank and the ability to take on bigger commercial jobs — parking lots, fleet washing, larger properties — without constantly driving back for water.
The Real Question: What's Your Job Mix?
Ask yourself honestly what your next 12 months of jobs will look like. If you're mostly booking $150–$300 residential jobs, a single axle keeps your costs down and your trailer easy to handle. If you're actively pursuing commercial accounts or expect to run full 8-hour days, the tandem axle pays for itself quickly in reduced downtime.
Don't Forget Tow Vehicle Requirements
Tandem axle trailers weigh more loaded, so confirm your tow vehicle's rated capacity before you buy. This is one of the most common oversights new operators make — always check your truck's towing capacity against the fully loaded trailer weight, not just the empty trailer weight.
