Switching from 12 volt to 6 volt batteries

Couple things to add,

That 12v fridge is bad news for boondocking. They are very inefficient. Normally only find those in popup style rigs. But, I guess you're stuck with it. Get more battery.

I like the Vmax line of 6vdc. And with those AGM, you do not need to put them in a battery box. They are safe in any orientation. That might allow you to get even more than 2 of them, but you do need pairs. Unless you look at the Vmax 12vdc AGM. I don't have the 12v, but I would trust the name.

The cheap club store batteries will need to be in a box, and you'll likely end up replacing them sooner. Depending on how you maintain them. Might or might not be worth the savings to you.

One of the main reasons I chose a Danfos compressor style 12V fridge /freezer was because the they are a favourite of the ultimate boondockers which are yachters. They can't use propane fridges because propane is heavier than air and could sink to the lower decks if there was a leak and could cause an explosion.
Our camping style is 98% dry/boondock camping. For 5 years, we camped with a 7.5cuft NovaKool fridge/freezer which when cycling used 4.4A. They are more efficient than absorption fridges using 1/3 less energy. They cool much quicker, for the same outer dimensions, have 1/3 more volume, keep more consistant temperatures in hot ambient temperatures and are not a fire hazard. We almost never needed our 2000W genny as we had 4 6V AGM batteries and lots of solar.

People who use the term"12V fridges are bad news for boondocking" have never had this kind of fridge. They are becoming much more popular for so many reasons as long as you figure in more electrical capacity(batteries, solar) if you don't want to run your genny.

I have a 6 cuft absorption fridge in my TT which came with the new unit. If it gives up the ghost down the line, a 9 cuft NovaKool will fit exactly in the same opening and as I already have plenty of solar and 4 6V GC-2 batteries and more room for extra solar, this is the route I will go.

That does sound like an efficient 12v fridge. My concern as a boon docker is I hate.........did I say hate?.... Generators. I'll do most anything not to use a generator. And I like camping year round. That include weather that gets down in the teens. I'd need enough battery to run my furnace to heat the the belly of the coach to keep the tanks warm enough. I can keep up with my furnace pretty easily with my solar, but I think if you tagged another fairly high draw unit on the 4-6v's it'd get critical. Bottom line is you really have to prioritize your usage choice. I want a furnace, a C-pap, no genny and winter. Prolly nixes the 12v fridge...for my boon docking needs.
