Nice one, looking forward to seeing it in position.Right I've bought a fridge .
Second hand 8 series dometic 3 way , don't work on mains but works well on gas apparently and 12v maintains the temps when driving. Its 5 years old , has 2 new electrical bits on it thst cost over 200 quid and I paid 200 for the fridge.
My reasons
Well if my fridge had worked from the off I would not have been changing it.
To buy a compressor one now not only would cost me in excess of £700 for the fridge but would also increase what lithium I would need to buy by another £700 and I'd need more equipment to recharge those batteries.
So for now this fridge which is in excellent condition cosmetically and should fit straight in with no cabinet modifications is the way to go for now.
Might have to do a fit fiddling with gas pipe and wiring connections etc but it will fit in the hole the original came out of and will look nice in there
