Locally, and at offroad parks, Jeep Wranglers Rule. The YJ is by far the best choice in my area. And usually 3-4" of suspension and 33" tires are plenty. Beyond that the trails start to become less fun and challenging, and the Jeep becomes a poor handling trailer queen beyond that.
For expo travel, pulling Jeeps or Bikes, and camping I prefer 1 ton trucks with solid axles and larger gas engines. I prefer tents over trailers as I stay in lodges/hotels when appropriate. Usually the 1 ton trucks from Ford, Dodge, and the olde Chevys have stout durable drivetrains that are great to build off from. No worries about weak parts. Usally the extra size deosn't hinder me. I don't expect my expo rig to need to go where my Bike would be better. Allthough I consider a normal 1ton as a "small" truck. I never have trouble with thier size.
I like to balence my trips between plush and rough. I'll rough it to camp in a scenic location, but I'm not camping in no KOA parking lot or any other campground with nothing more than a parking lot style to offer, better off just finding a decent hotel.
I like trucks with:
-At least a Dana 60 up front
-long beds, which usually have larger fuel tanks
-shorter wheelbases
-300-350 hp, 400+tq.
-auto trans and a Detroit Locker in the rear, open front diff.
-3-4" of lift and some improvement in articulation. I prefer BDS kits. (But stock is fine if you don't need a little more articulation or only plan on 33" tires)
- 33 to 36" hybrid tires like the GY Duratrac, Kelly GSR etc.
- at least 4.10 gears for a stock truck, 4.30 for any kind of decent tire, 4.56 for 35" tires.
I avoid IFS, LWB crewcabs, 2wd's, and diesels. IFS is kind flimsy and I can't tune them to ride as plush as I can a solid axle. LWB CC's high center too often for me, one of my neds is to cross a roadside ditch at 45 degrees. Diesels are usually too heavy and break through frosted mud roads more often than gassers. Best off road modification I ever added to my truck was a Honda CRF450R.
