Choosing your configuration

Which trailer sizes are available?

The published DEP configurations use 6 × 12-, 6 × 14- or 6 × 16-foot dual-axle trailers with 300-, 400- or 550-gallon water options. The quote specifies the combination for your build.

Is the listed 8 GPM available at every hose?

DEP offers 4–8-GPM equipment and single- or multi-line configurations. Ask for the output available at each line when operators work simultaneously; the highest system output is not a separate allowance for every hose.

Is DE the same system with a shorter name?

No. DE is a cold-water mobile vehicle wash platform. DEP is an enclosed hot-water pressure washing platform. Compare DBP for an open-trailer hot-water alternative.
