We have a toy hauler and are also fully contained, but I prefer campgrounds with hookups because I enjoy long showers (need lots of water and a dump) and electricity without having to run the generator. We can run off the batteries for a few days if we don't run the AC, but in Southern California, we usually need the AC! We have three ACs on our rig and the garage has its own. To run the AC we either need to be hooked up or running the generator. The fumes coming from the generator when it's running is just as bad for the birds as the campfire smoke when we have our back deck down for them, depending how the wind blows. For my own birds, I don't avoid campgrounds with campfires because we can seal up the garage of our toy hauler completely. It has it's own door, so even when we're walking in and out of the trailer and bringing the smokiness in with us, the smoke isn't getting into the garage (aka bird room). We have a sliding glass door between the living area and the garage, so we can easily see what's going on in there.
