E loop is OK for tents and smaller campers or RV's. Fairly level with a few rocks good shade. Lots of raccoons so watch your food. You can check the pad lengths on Recreation.gov. I prefer to camp at one of the walk in sites on H loop but you have to take whatever is open. For some reason E loop is always the last loop to fill up. I live in Tulsa and I would love to come fish with you guys. However I have medical issues that prevent me from fishing or camping any more.
