Smoky Mountains camping

My family and I are planning to go down to the Smoky Mountain area in late July/early August this year for ten days, which will be three days travel there and three back, and then six there. We're brand new to RVing (but not to tent camping). We're trying to do a mix of hookups and dry camping. For the dry camping, we'll be exclusively staying in the national forest campgrounds. However, for the days we'll be taking advantage of hookups, I'm in need of some advice.

I'm looking for out of the way, state/national forest type camping, but with hookups, well at least electrical. In other words, I like secluded forested type camping, not large open fields with RVs on top of one another. I've never cared for the KOA type camping experience. I've always looked for ma and pa type small establishments with more privacy (if I'm not doing state/national parks or dispersed camping). When tent camping, it's much easier to just show up and look for open sites. Now that we're giving RVIng a try, we want to have reservations first for our maiden voyage. So, I'm hoping some of you guys can give me some recommendations given what I'm looking for down in the Smoky Mountains.

Thanks!
