When I was deciding what to buy originally, the price difference for the isolated unit was small, so I weighed all the different concerns I could imagine, and decided to go isolated. One concern that swayed me was I didn’t want to tie the 120VAC ground of the camper shore power system to my truck ground in case of some wiring fault at a campground. . Now that I have realized I will never hook up my 120VAC anywhere but at home, it’s not a concern.
