No way are you going to put a driver's door in a DP...too many items in the side dash. In a front crash you are high enough in a DP that most vehicles are going under you. Does she drive a smaller vehicle...better switch to a F550 as a daily driver. Other than DynaMax most of the Super Cs have the "quality" of a regular C. If the seats do not turn around you loose 8' of your length...5' if they do.
Before going residential I had to run the generator 2+ hours/day when dry camping...big RVs are energy hogs. My generator time has decreased because I added a 100A charger to the battery system for the 21 cuft residential refrigerator that draws 96W when running. I recently went from 42' to 45' and out West we boondock 5 out of 7 days...it's not true you need 36' max for public CGs.
