Just because folks have towed with such a rig with no problems doesn't mean that it's safe....maybe luck is just on their side for now. Strongly suggest you do your homework, get ALL your numbers together with the specifics for your vehicle, then you can get more precise help that "with no problem". Load up the family in the vehicle with whatever stuff you'd normally take and head for the scale at a Pilot, Flying J, Love's or similar. It'll cost you maybe $5 for a real number to work with. Don't forget to add about 1000# wiggle room to your numbers. That's a BIG trailer and it's your family we're talking about here, no room for guessing or letting emotion cloud your thinking. You're doing this the right way. Good luck.
