We take the grown children and grandson often.......
If you pull your camper on flat ground you will be fine with the trailer that is a little longer.... The Weight Police will make you think that your set up will magically self destruct or be unsafe if you are at or just over capacity that is simply not true......... The worst case will be if your running over or at capacity is loosing your transmission...... keep the fluids changed for severe service applications......
We went bigger at 36 feet with a toyhauler to give the kids a private room & the capability of carrying our toys :) So we can no longer use the 1/2 ton at 14500 lbs..... but having 4-5 queen sized beds is nice when you need them :)
