plus the xterra's higher center of gravity over the pathfinder, also factors in the lower tow capacity.
the 189's actual weight, from the factory will be at least 3600lbs.
add the weights of water, propane, battery and cargo, plus subtracting anything other than a 150lb. driver in the xterra, will put you near the xterra's max.
most on rv forums, swear by the 80% rule. don't tow anything over 80% of the TV's max.
if you were only going to tow on flat terrain, then you can get by. but if you plan on mountains/hills, you'll be hating it.
i absolutely love the xterra, but when we were shopping for a new TV, it just had too many negatives to be a viable tow vehicle for a full height TT.
