Water Pressure Regulator

Device installed on water hose attached to city water to limit the water pressure entering the RV. Most regulators limit water pressure to 40 psi.

Weight-Distributing Hitch

A ball hitch system that distributes some of the tongue weight to all axles of the tow vehicle and trailer. With standard ball hitches, all of the tongue weight rests on the tow vehicle’s rear axle; the weight-distributing hitch uses spring tensioned bars to distribute it among the axles. This provides more weight on the front axle for better steering control, and less weight on the rear axle to allow towing a heavier trailer that may otherwise overload the rear axle.
