This could be suitable for a large rig since there are no real designated sites. You can camp anywhere between the road and water. The road is gravel but not packed very well then turns into dirt so be cautious if wet. Easiest way in is WY310. Take a right from there and then you’ll take a left to drive around the reservoir. The cords are pretty far in, you don’t need to go that deep. Usable T-Mobile and at&t service
