Getting it through the
door is the first issue but providing the required clearances in the cabinet is also important. I wanted a model with the coil on the back not built into the sides. I first bought Magic Chef/Haier and returned it right away. They said do not run on an inverter and in my case they meant it. Others may have had better luck. My door opening is 27 3/4 and the frig measures 24 wide but puckers out at mid point on the sides probably because of the insulation inside.
Whirlpool was one that only required an inch or so on the sides and top. I dont remember all of it exactly as it's been almost a year since I installed mine. As my updated post shows this Whirlpool used 70 amp hours in 24 hour time frame and that included at least one defrost cycle.
If you are just going to local campgrounds cool it down before you go and plug in when you get there.
If you are in a campground and the power goes out for many hours, yes you may want to be on an inverter.
If you are traveling many hours per day you may want to move it onto an inverter and let the tow vehicle keep it running.
If you are boondocking a lot you will be on an inverter and will be best off to go with solar or run the generator a lot.
I guesstimate my risk with all the modifications that I do and give this one about a 3 year window. It cost me $485 delivered from Best Buy. If it only lasts 3 years that equals $161 per year or the equivalent of about 2 tanks of diesel. I would never go back to using a propane frig.
