Is a 28 foot TH too much for a 2013 F150 with 5.0 V8?

Tvov, yes it does. While it is rated to handle the weight, my fear is that if I "push the envelope" to borrow a flying term, I reduce the safety factor and the rig would be very sluggish in fast interstate traffic.

I very much appreciate all these comments!! I think I will pass on the bigger trailer and go with my original plans. Thomascrnj
