RV Hydraulic Repair & Hose Manufacturing

Hydraulic systems power your RV's slide-outs, leveling jacks, and stabilizers. When they fail, your RV is stuck — literally. AM Mobile RV Service not only repairs hydraulic systems on-site, we manufacture custom hydraulic hoses right at your location. No waiting for parts to ship, no towing to a shop.

RV Hydraulic Systems We Service

From simple single-cylinder slide-outs to complex multi-jack leveling systems, we service all major RV hydraulic brands and configurations. Our service truck carries a portable hydraulic hose crimping machine, fittings, and bulk hose — allowing us to fabricate replacement hoses on the spot.

Slide-Out Systems

HWH, Lippert, Power Gear — cylinder reseal, motor replacement, valve body repair, alignment adjustment

Leveling Jacks

Bigfoot, HWH, Lippert Ground Control — jack cylinder repair, pump service, controller diagnostics

Hydraulic Hoses

On-site hose manufacturing — custom lengths, proper fittings, pressure-rated for your specific system

Pumps & Reservoirs

Pump motor replacement, reservoir cleaning, filter service, pressure relief valve adjustment

Common RV Hydraulic Problems We Fix

Slide-out won't extend or retract — cylinder seal failure, valve solenoid, or pump pressure loss

Leveling jacks not responding — controller diagnostics, solenoid testing, wiring repair

Hydraulic fluid leak — hose replacement (manufactured on-site), fitting tightening, cylinder reseal

Jacks extending unevenly — individual jack valve adjustment, sensor calibration

Pump running but no movement — internal pump failure, relief valve stuck open, air in system

Slow slide-out operation — low fluid level, worn pump, or restricted filter

Hydraulic system making grinding noise — pump bearing failure, cavitation, or air intrusion

Jack pads sinking — ground pressure assessment, pad replacement, jack extension limits

On-Site Hydraulic Hose Manufacturing

One of our most unique capabilities is on-site hydraulic hose manufacturing. Most mobile RV technicians can't replace a blown hydraulic hose — they have to order one or send you to a hydraulic shop. We carry a portable crimping machine, bulk hydraulic hose in multiple sizes, and a full assortment of fittings right on our service truck.

When a hydraulic hose fails on your RV's slide-out or leveling system, we measure the old hose, select the correct pressure rating and fitting type, cut the new hose to length, crimp the fittings, and install it — all in one visit. This capability alone saves our customers days of downtime and hundreds of dollars in towing fees.

We manufacture hoses for all common RV hydraulic systems including HWH, Lippert/Schwintek, Power Gear, and Bigfoot. Each hose is made to the manufacturer's pressure specifications and tested before installation. This is the kind of specialized service that sets AM Mobile RV apart from other mobile technicians in the Texas Hill Country.
