I can see why the OEMs are dropping the LP fridges. Maybe safety as well as reliability. They were nice for boondocking but very unreliable getting or staying cold, with some exceptions. I see and read a lot more about the RV OEMs trying to go more toward electric powered appliances instead of LP.
But total electric RVs and no LP has its own issues, they come with big power requirements and could be a problem for off grid. I really like the LP furnaces and stove operations!
Our Dometic 18 cuft has a real hard time cooling in warm/hot weather, always has from day 1. We had hoped to convert it to JC Refrigeration 12V compressor but things happen and we didn't get it done.
With the construction of new RVs and the addition of solar panels and power storage advancements, the 12V compressor fridges or residential fridges and inverters , are more reliable. The trade off is they do take more electric power to operate. Owners that boondock a lot have more to think about generating and storing enough power to last X amount of days, and you have to compensate for not being able to generate enough solar power on some days.
