This was one of the issues with Weekend Warrior when we bought ours. I made the dealer take it to CAT scale wiegh it just the way we bought we the options installed and a full fuel tank. No water, It was heavier than advertised but still within our range. I haven't wieghed it yet with all our stuff but in calcing everything we are probably just under the max weight. We do not tow with water until we get close to our destination.
I would suggest if anyone buys one you have weighed by a certified weigh station just to have it and just in case.
