Thoughts? Well, Mojave NP is great for camping out of a Jeep. I've been there a couple of times, camping out of a mostly stock Jeep Wrangler (TJ). The roads there generally aren't too demanding, though I did get turned around once by a washout that maybe a really built up rig could have negotiated. Park Service rules allow you to camp out of a vehicle most anywhere that there is an established camp site (ie. a fire ring). I've camped off of Kelso Road, Pipeline Road, the Sunrise Rock camping area near Teutonia Peak and off of Wild Horse Road near Hole-in-the-Wall. There's tons of places to camp, some of the most accessible ones are shown on the Park Service, Tom Harrison and Trails Illustrated maps, many others are not. My first visit, December 2012, driving across Cima Dome and camping a second night near Sunrise Rock, there was snow on the ground and I was worried about getting snowed on while driving across Cima Dome through the wonderful Joshua Tree Forest that lives there. At that time, the Mid Hills area and pretty much everything east of there was inaccessible due to ice and snow. The point being that Mojave actually has some relatively high elevation areas. If I was going out there this time of year, I'd probably focus on the New York Mountains, Caruthers Canyon or maybe Castle Peaks areas in the higher, eastern half of the preserve. All of those are places I haven't been to yet- If you do go, please post a trip report!
