Hi Guys, I'm new here. Just signed up. I have an 89 Northern Lite camper and the original fridge kicked the bucket. It has a blockage in the line somewhere that I can't get rid of. I picked up a Dometic RM2310 fridge off craigslist that works great. It has the same dimensions as the original 2301, looks identical as far as the guts are concerned. I just would like to know what the difference is in these two models if anybody knows.
