Generally speaking, roaming around the USA (usually out west), I've always been within a few hours of some kind of food or a gas station. Otherwise my "expo" traveling is really about what else I have to bring along? My wife and I usually take two weeks off each year for a trip that's at least half camping in the woods. I find a Wrangler
very cozy for two. My first trips with my TJ were just done by removing the rear seat, consider the weight and usefulness of everything, use duffle bags that fit to every inch of available space, a cube-sized cooler, and we had a lot of fun trips!
Two summers ago I did add a small hitch rack for a new tent, better chairs and even a table. That made the trip a little more comfortable.
This year I also added an off-road trailer, which gave me even more room then I knew what to do with?! (Cots were added, a larger, better cooler, more beer and an ENO hammock!)
My next addition is an RTT that is showing up on Monday for the trailer. I've worked hard on my Jeep. It's nicely built for a good ride and handling on and off-road, gets me where I want to go, and has the ability to safely tow a small trailer. I have no plans to ever change from my two-door Jeep.
