everything has pretty much been covered but from our experience wife and i
33ft tt
1 living room slide (with slide in bathroom is open, fridge is not but only takes seconds to open slide enough to open fridge)
i put about 10 gallons of water in fresh tank to use bathroom and wash hands on fuel stops or rest stop lunch. love being able to use our own restroom and not public restroom and makes for quick lunch
does heat up inside on hot days but we dont dry camp or boondock. shore power and ac cools TT down fairly quickly
at cg, if we are not going out site seeing or other things usually leave truck hooked up unless site is too short, normally not a problem with backins or pull thrus. doesn't take long to unhook or hookup wdh after you have done it a few times.
