Can't speak for others but we routinely dry camp with a residential fridge and have for a few years. We run our genny 45 minute to an hour per day mostly during meal preparation so we can use the microwave, toaster, Kuerig coffee maker etc. On a day to day basis our TV draws more amp hours than our fridge. A robust solar system should be considered as part of a residential fridge install. We have dry camped with others who also have residential s with solar systems who also experience no problem. My advice would be to seek advice from users of residential fridges in RV's. There are really no downsides and anyone who has ever switched will tell you they would NEVER switch back. If shopping for another motorhome I wouldn't rule out a unit that had an absorption RV unit but I would have to build in the cost of switching to a residential.
Good luck in your quest and happy camping.
