I've used the Marina campsite on the edge of Bath, Bristol side, next to the Bristol/Bath cycleway, along an old railway line. Easy walk along river to Bath and level cycleway into Bristol. Pub opposite as well.Other than Baltic Wharf, which seems permanently booked up, are there any other options for camping in Bristol? Can’t see anything.
There is a site outside Bristol https://www.brooklodgefarm.com/gallery/ which looks very nice. I've visited people there, but never stayed. It's just off the A38 after Redhill, but not on the Airport Flight path.
There are also a number of sites around Long Ashton that are there for Festivals and the Balloon Fiesta. They would be basic facilities only.
The VW California Club is the worlds largest resource for all owners and enthusiasts of VW California campervans.
