We have a small 20' camper and are wanting to camp in the first come areas of either Shoshone, Bridger or Grand Teton.  We are coming from Devils Tower.  I know its Memorial Weekend and will be crowded but we are hoping the first come areas will have access.

We are wanting to make a base area and then do day trips to Yellowstone, etc.

So any recommendations for primitive camping? Don't need water/sewer/electric, etc. Some hiking and scenery would be cool.

Thank you very much for any replies!!!!!
