We love our residential, BUT, we rarely boondock. My understanding is you need a lot of solar, and possibly a BU generator, to keep your batteries happy

Thinking about getting back into Raving. Two things I don't want in a new RV are propane and a black water tank. There are much better alternatives that provide the same functionality at lower cost or at least less maintenance.


I'll bite. Give us the lowdown pls. Thanks.

I guess we have been lucky over several decades of utilizing absorption fridges as we have always had good success with all our RV fridges, properly installed they work quite well and there in lies the number one reason they operate poorly. A mobile RV Tech who knows their stuff will easily identify issues pertinent to improper installation and should be able to improve or correct situation. Nothing wrong if you decide to go the compressor fridge route, certainly the cheaper more economical solution although adding costs of batteries and solar array will eat up any savings. Class A rigs and 5ers have been offering compressor fridges well before 2017, although I would stay with absorption style due to their ease of use while off the grid.

Ice cream is not something I keep around because it's not good for me. My gas Dometic keeps things just fine, maybe not as cold as a resi but good enough. Uses very little fuel and hopefully will outlast me.

Alternates to propane are heat pumps, electric and diesel. That may imply a large gen possibly 120/240V, solar, larger batteries. MW can do some cooking. But electric oven/cooktop seems like the best alternative to propane while diesel might be possible. Composite toilet?

Apparently propane BBQ, campfires etc with portable tanks would not be accepted.

We had one 5th wheel with a big residential unit and it was okay as long as it was parked near power. Haven't tried solar, we use generators still. But that fridge pulled lots of power using the inverter. Two group 31's didn't last long. Adding lots of batteries takes up too much room IMO. Propane fridge keeps my ice cream frozen solid in 100 degree heat, haven't had one fail yet. Had three RV's over many years with two Norcolds and one Dometic RV fridges. They all cooled fine.

I prefer the regular size fridges, never had a huge one. If I need more room I rather use a 12 volt powered portable unit stored in the basement. The portable 12 volt coolers can go in the car or truck for grocery runs too.

Opening the doors often will warm one up in a hurry.

The trend seems to be larger RVs more along the lines of a smaller house that is used pedestal to pedestal. There are very efficient 12V and 120V refers available of various sizes so no need to wait very long for one to cool down. But the electric power has to be provided.

If you want to switch to a compressor refrigerator, spend the money and get a compressor refrigerator made for 12v use. You will need way less solar, or way less generator when the sun does not shine. I would recommend Nova Kool.
