TL;DR: The e2 hitch performs well on pavement, but it goes bad if you tow over uneven terrain.The e2 hitch came with our 20' 2019 camper. It's fantastic for weight distribution, and offers amazing sway control; the trailer tracked true at 55 mph with a 40 mph cross-wind, even when the blasts from passing heavy trucks would cause the driver-side mirror to fold in. More than once. I was pleasantly stunned.So ... just two stars?The thing is, we're often camping in the wilds of CO, WY, MT, UT, NM, or AZ. Our trailer even has a 3 lift to allow for more difficult terrain. And when the going gets lumpy, the e2 goes wrong.Perfect camp spot! But the approach is rutted. At times, the 4Runner tilts to the left while the trailer tilts to the right. This puts enormous downward force on the left spring-bar where it meets the L-bracket. If, at this moment I also turn to the left, the spring-bar does not slide against the L-bracket. Instead, it forces the bottom of L-bracket mounting plate to slip back along the trailer frame. (And that's after overtorquing those plates with a 16 breaker-bar!)This is bad:A) the L-bracket is now too far away from the hitch, and the spring-bar could slip off entirely in a tight turn.B) the spring-arm no longer lies flat against the L-bracket, but rides instead on the back edge of the L-bracket. This dramatically reduces the sway-control, and damages the L-bracket by grinding that edge.To address this, I drilled a hole in the trailer frame on each side behind the L-bracket mounting plate, and screwed in a hardened-steel bolt. I figured the force would never be enough to shear this hold-bolt. Indeed not, but the trailer frame around the hold-bolt hole deformed, as seen in the photo, under the load place on it by the L-bracket plates. My fix wasn't enough.Now, I could re-drill a larger hole, put it right through to the other side of the frame, so as to install a hold-bolt all the way through the frame (rather than just screwed into it). Maybe that would finally put an end to the problem of slipping L-brackets. Or I could get someone to weld them in place.But this should NOT be necessary, and suggests that the e2 hitch is simply not suited for our kind of camping. The L-brackets simply can't withstand the forces involved in off-level conditions.If our camping were confined to RV-parks, State Parks, and the like, the e2 hitch would be great. As I said, the weight-distribution and sway-control are terrific. It is a bit noisy, although that's normally tolerable from inside the tow vehicle.But the e2 hitch just is not designed for--and can't realistically be adapted for--travel over uneven terrain. I'm in the market for a hitch that can handle rough country.
