I read through the whole manual and I don't think I saw a single mention of the maximum allowable/safe incline in either 2 wheel drive or 4 wheel drive. Does anyone know what I can safely do with no load except passengers? I,ve got some trails on my property that exceed 20 degrees in some places.

I've done 48..50 degrees in 4wd with no problem...but I think about 52 is the limit for me. If it's rocky or smooth will make a difference. If the front starts lifting enough that steering is effected...might consider that your limits...or set someone on the hood...lol

Got mine pretty steep
