usmcshepherd, I would recommend that you stay at Lizard Creek Campground. Beautiful and Original Park Service style campground. Your rig will fit in there too. Plus you have cell coverage there.
The Tetons' campgrounds are starting to fill up so people should plan on securing their campsites before 9 AM in both parks through mid August. The larger ones, Gros Venture and Grant, will fill mid to late afternoon.
The parks are certainly worth visiting, no matter how crowded they become. But you should arrive with the knowledge that many of the places will be filled by people knowing the summer season requirements. As well as parking and pull outs at many of the popular places will not support large and extended vehicles.
Have fun and do your planning before arriving in the National Parks, this season and for ever after.
Safe travels, my friends.
