I have an RNR 716 Powersport 3-place, all aluminum trailer, got it new in 2002 so we're coming up on 9+ years. Multiple 600 to 800 mile trips to the UP most years, use it in the off season to haul my small JD tractor and have also used it for hauling lumber and moving furniture. Replaced the brakes/bearings twice (rusted brakes) and the wiring once (yep corrosion) and new tires once. No problems with the aluminum frame. Multiple 600 to 800 trips to the UP most years, use it in the off season to haul my small JD tractor and have also used it for hauling lumber and moving furniture. Not sure if it matters but it has torsion axles, maybe this has helped the longevity, don't know. Will buy another one some day, but this one is still doing the job holding together well.
