A lot of the campgrounds beside Fishing Bridge have dump stations. I know the one at Bridge Bay is useable by large rigs as I've dumped when leaving with my 35' FW.
Fishing Bridge fills up early because it has hookups and it seems a lot of people can't go without. But after riding through it, there is no way I could stay in the parking lot of a campground.
After 2 stays, I've found Bridge Bay to be convenient to everything on the south loop, very easy for large rigs to negotiate, and good separation between sites. But I'm looking forward to going back with the TC to enjoy the smaller more rustic campgrounds.
