Hi, We stayed at Montgomery Bell in 1999 and we loved it we had a wonderful time. I would thing the sites or some of them would be able to accomodate you here's a pic of our site and we had a pop up with a truck and our screen tent set up on it and had plenty of room. I've enclosed a link to 2 pics we have of our site and one of the lake at Mtg Bell. They have a lodge there that we were able to use also that had a pool and an enclosed pool and a hottub Mtg Bell is about 20 - 30 minutes (40 Miles)from Nashville so we visited Nashville several times that week and it's about the same distance to Cookeville, Tn we always went to Dixon to buy groceries or shop. It was a beautiful camping area, they have some old church and stuff on their property and walking trails. We even went up to the Main Ranger Office for a birdwatching demonstration

It is kinda in the middle of nowhere there is really nothing else there. So if you're wanting to do other things expect to drive a good ways. There's several nice campgrounds at Nashville so you might consider staying there that probably allow bigger rigs.
You'll have to click and paster this and I think to view the pics you have to enter some registration info. Hope they help some.
