We have Keystone x-lite 30 ft 7000 lbs 5er my 2014 F150 pulls it no problem.

This is where Ford has it nailed!!!!
The F150 EcoBoost and a Max/Max package will tow a nice sized lite 5er. I would say also much safer than a TT! Pulling a 33' 5er or a 33' TT with the 5er you would arrive at your destination much more relaxed than with the same length TT!
No sway issues no issues with expensive sway fixing hitches. That and only self sliding 5er hitches weigh 250#! Mine weighs less than 100#.
