OK.. so I was planning on using a 12V cooler in the trailer instead of a 3 way fridge (propane is not DIY friendly!)

Well I went out looking at portable power sources - basically a large battery pack. Most of the regular type (like the battery boost packs) will run the thing for 2 or 4 hours... not enough - but I did find one large one that will run it for 14 hours... BUT - it then takes 16 hours to change it back up

SO now I'm thinking I may have to go back to the 3Way. I have the 3way out of Mom old camper - it works fine.. also have the stove, both just need some cleaning up. I'm going to ask about installation at the local camper sales place, but just wondering if anyone has had one installed in a DIY LQ. I'm really wondering if I can install one on the goose neck wall... the original reason I abandoned the 3way was that the supports in my trailer side walles were too close together to install a fridge with out messing with supports - I don't want to go there. But there is pleanty of space on the GN wall.

Any other ideas for a fridge - or way of running my 12V cooler would be great too.
