I've been using TH's for 20+ years. And for more than hauling jets.
I have a Heartland FUEL 305 which is the camping world brand. I paid $34k out the door for it about 3 years ago. That was a price that I couldn't refuse.
It is 30 ft long, bumper pull, on board fuel and genny, all season rated, 100 gallon fresh water and has a kingbed in the upfront room.
I would suggest a bumper pull TH because, as a general rule, they have a bigger garage AND (and this is the keeper) you get to keep the bed of your truck to haul MORE stuff if you need.
The onboard Generator runs off of the onboard fuel so you may have to alter how the generator gets gasoline if you use the on board fuel tanks for kero/diesel.
I went with 16" wheel dual axles and the rig weighs right around 8k#'s empty.
Even for events when you aren't bringing "toys", having a large door in the back to load/unload stuff at the camping site is tremendously helpful. You aren't trying to bring all the junk, food, campfire, etc.... through a small door on the side of a Non-TH.
TH for the win.
