For us. The TT weighed 600lbs over the factory weight as it was WEIGHED at the end of the assembly line.
What we added includes a camp stove, 10 folding chairs, one grill, sheets, & blankets for all beds, a tent, a dining fly, towels wash rags, 1 metal folding table, 2 plastic folding tables, pots, pans, silver ware, cups, some games, a hammock, and hammock stand. A folding chair carrier to roll things to the beach on, some clothes, and some food. Also leveling blocks, chocks, water hoses, and sewer hoses, and about 5 gal of water in the black tank. and 2 empty coolers. and of course gas in the tanks, and a battery. Also 2 cooler / camp stove stands, and stick biscuit cooking sticks. Plus a 20' awning matt
Yep all that came to 600lbs. Honestly. there isn't room in there for any more stuff.
