My short list would be Range Rover Classic, Land Rover Defender 90, Land Rover D2 (because its like an ex who is crazy but does some wild things when you want them too), OJ era Bronco, First Gen Explorer SAS, 9th Gen F150 (1992-1997), 7.3PS F250.... J80 Land Cruiser, LJ Wrangler.... K5 or K10 blazer. I have different ideas for all of them, but my two favorite ideas are a RRC with a big new engine in it and some 37s. or a prerunner 9th Gen F150.
New cars my list is basically Raptor maybe Bronco. The Gladiator is kind of cool too, but it fails at being a truck and a Jeep but its kind of cool still.
