FWIW: An option I believe worth considering is to get rid of the hydrogen-charged unit (think Hindenburg) and replace it with a helium- charged unit. A residential would work OK for me as I am a "pole-to-pole" camper, but a potential buyer for my rig some day may well prefer boondocking .... as many do.
One could install a new cooling unit as a DIY project, but I will likely plan a trip back East to have it done next spring. Kinda pricey, but I feel I need to do something as my "working just fine" OEM Norcold is getting long of tooth at 11+ years. The extra capacity that this outfit touts sounds good too. http://jc-refrigeration.com/products/ and he has really great reviews.
In any event...........safe travels. ed s
