Custom 7x14 Super Duty Pressure Washing Trailer — Hot Water + Triple Soft Wash System

This is a super heavy duty 7x14 pressure washing trailer, custom built from the frame up in Oregon City, Oregon — with reel racks and MoFlow racks built directly into the frame, upgraded axles, and a lifetime frame warranty. Two Honda-powered pressure washers, hot water, and three independent soft wash systems make this a complete washing operation for a serious multi-service crew.

We ran our own washing rigs for over a decade before we started building them for other companies. Every decision on this trailer — the aircraft-grade aluminum, the 316 stainless hardware, the fully ported plumbing — comes from years of learning the hard way what holds up and what doesn't.

About Expert Power Wash

Expert Power Wash is a family-owned pressure washing equipment shop in Oregon City, OR, run by Tim and Kristina. Before we built equipment, we ran our own pressure washing business for more than ten years — so the parts and chemicals on our shelves are the ones we trust on real jobs.

Our storefront stocks thousands of parts, chemicals and supplies, most in-stock orders ship the same day, and when you call 503-403-6185 you talk to people who have run this gear.

Pickup & Delivery

Due to their size, our builds can’t ship standard LTL freight. We arrange private transport through a trusted local transporter who has delivered our skids and trailers all across the United States — rates vary by destination, so we quote delivery on your discovery call.

We strongly recommend picking up in person (or flying out) to take advantage of the free hands-on training and full walkthrough of your new rig. FREE local pickup at our Oregon City shop, Monday–Thursday 8am–4pm.
