Hey, new Forest River E-Pro owner, having decided to "go back to my roots with a pull behind after last 20 years of owning Class C's. With kids gone I decided driving a "house" down the road wasn't really necessary anymore. Very happy with the quality and ease of use of the E Pro, just what the doctor ordered! But I was immedeatly reminded of the joys of white knuckle driving on highways/bad roads with a lightweight and bouncy trailer. Was going to buy one of the load leveller hitches but then discovered another option. Company called Base Air out of Australia manufactures an air bag supplementary suspension system for trailers and trucks that sounded almost too good to be true. They needed to put some systems on various vehicles (semi's, RV's, large cargo vehicles, etc...) as a test bed to showcase to US industry. I managed to convince them my E Pro would be a great option for them (helps that a cousin of mine was working for them here in US as a consultant, and I was the only person he knew who actually owned an RV helped LOL). So after the installation and many miles, I'm convinced these suspension systems are going to be standard options on US RVs in a few years. Revolutionary describes how much more controllable pulling a trailer is with this system. Air bags for each wheel that activate multiple times per second to level suspension in reaction to bumps, swaying or shifting center of gravity is phenominal ! No more white knuckle driving at speed, no more fighting rebound bouncing every time you hit a bump or uneven spot. The camper basically anchors and stabilizes the tow vehicle. Highly recommend everyone watches for this system coming out in next few years, it's going to revolutionize how we deal with towing campers or driving our "big rigs". Check out Baseair.com !
