I have 2 Sleeper OPUS and I have not had any issues with hauling it with my 4runner. Granted I re-geared to 4.88s, but even before I re-geared, it was not an issue. Offroad wise, just make sure you have the right RATED recovery for your vehicle and trailer (Weight) should you need to recover. As far as off-road trailers go, it is a heavier option, but a more luxurious one. Most of the issues that pop up are unique to each individual trailer. There is 'opus camper owners group' Facebook page that talks a lot about Dealer issue, troubleshoot, trailer hacks, and other mods.
