If you can, before you buy, visit some CG that you like or wherever you camp. See if you can make it with something bigger. With USFS sites its not always the length of the site, but the interior roads. Some are not build to handle a longer rig being able to turn around or back one in. Look at other rigs in the area or talk to a Ranger (good luck on finding one) and ask them. If you're purely boondocking then I'd be looking for something that is build solid and for use off road. Assume you've looked at the Desert Fox line up already.
