I have a 2012 WhiteHawk Jayco 28’ that is about 5800 dry and I guess may max is around 7000 fully loaded. I currently tow with a 2011 F150 5.0 with HD towing package and drive around 20k miles a year with 5-7k of that towing miles.
We have about the same set up. Mine is a Keystone 30ft bumper to tongue that weighs in about 8,000 lbs or less. My tow vehicle is a 2008 Ford F-150 4x4 Supercrew. Tows it great with plenty of power.I use an equalizer hitch/sway bar and the truck has E rated tires and air bags (because I haul a lot of firewood).. Doesn't sway anymore than with a 2003 Chevy HD 2500.......A fifth wheel will pull much better on the hi way as far as sway goes.
And yes, a 3/4 ton or more is a better fifth wheel tow vehicle but not necessarily better on travel trailers. I have done both and still alternate between a 2003 Chevy HD 2500 and my truck towing and on my trailer and a wood trailer that weighs in at 10k loaded, there is little difference, if any.
