I have no idea how old you are but are you planing to take one of these rigs into retirement?
If not a smaller fridge is just fine. You can always go to the store or stop by Walmart, if you happen to be on an extended road trip they are everywhere. In fact if on a road trip you will probably spend a night in Walmart anyway. Living full time in the unit I MIGHT change my thinking.
As far as A/c if sized correctly one will be fine. You may want a small fan to move air around if there are obstructions to good flow in the rig. If 2 A/C you may be looking at needing 50 AMP service to function correctly. Do the place you normally go offer 50 amp service?
