All canming loops (i.e. not cabin loops) allow both tents and RVs in the same loop.
As CLynnJones suggested you could share a site, or if that would be too much you can choose a loop of the type service you want.
There are 3 levels of campsites at Fort Wilderness:
Standard, which includes electric and water This includes the 1500 and 2000 loops
Full Hook Up, which includes electric, water and sewer (most of them are this way) This includes the 600, 800, 900, 1000, 1100, 1200, 1300, 1600, 1700, 1800, and 1900 loops.
Preferred, which includes electric, water, sewer and cable TV The preferred sites are also in loops situated closer to the settlement which includes the marina, beach, restaurant, petting zoo and many other activities. Also, if you plan on using the cable TV hook up, remember to bring a long coaxial cable to hook up with. If you don't have one Disney will be happy to sell you one.FW Camp Site This includes the 100, 200, 300, 400, 500, 700 and 1400 loops.
The other thing to keep in mind is pets. Some loops are designated for pets and you may want to as for one or to stay away from one as your preference. The pet loops are hook up 800, 1600, 1700, 1800, & 1900 loops or the 300 or 700 "preferred" loops. The 500 loop is an overflow preferred pet loop when additional pet sites are needed.
