Since that model trailer is no longer on the Forest River site, I am going to compare it to the current "23" models, which are 24 to 26' long, with a GVWR of ~7500 lbs.
Since you have mentioned several pickups and other parimeters, any make 1/2 ton truck, big engine (~300 hp, 350 ft./lbs. torgue or above) , low final drive ratio (3.73 or lower ratio, higher number), factory heavy duty tow package, long wheel base (over 130" or so), crew cab should work good. Don't expect any tow vehicle to pull without effort, especially in the mountains.....that just ain't a gonna happen. Even diesels grunt some going up mountains.
If you are planning on carrying a bunch of heavy camping stuff in the truck, along with multiple passengers, you need to be aware of the GVWR. Some of the current Wildwood 23s have listed tongue weights over 600 lbs., and that could "grow" to 800 lbs. depending on loading. Even though a WDH will put some weight back on the trailer tires, you might still have 500 to 600 lbs. of weight added to the truck with just the trailer. Add another couple of hundred pounds for just 2 passengers, plus whatever other passengers, plus cargo could approach the typical 1200 to 1400 lb. payload of 1/2 ton trucks. A 3/4 ton truck may work better.
