I'm new to the whole camping world when I look at the map to pick a site it shows RVs? I think does this mean they dont allow just tent camping?

I think you're allowed 2 tents on a site or 1 camper and 1 tent.

They allow tents

We just tent camped there last weekend! The sites are set up for RVs but we used tents as did others there. Go for it!

Pretty sure you can tent camp. No discount though. All sites have electric, whether you connect it not. Water is usually close, but not dedicated to the site.
