I for one will keep the Norcold. i have swapped out the OEM cooling unit for Helium, added extra exhaust fans, and added an internal circulation fan, not those stupid fans on a plate that hardly do anything. I maintain 34 degrees in the box in 65 external degrees or 110, doesn't matter.
As for powering a residential; I have 1/2kw on the roof with 4ea. T-145 batteries, but with bedtime running around 2AM with TV, Sat Rx, PC, heaters, a few lights, etc., I can easily be at 65% in the morning, and its just not worth the extra load. Doesn’t mean I can’t swap, but why?
Running on shore power: same 2006 OEM board, no signs of heat or charring anywhere. Making sure those spade luge are TIGHT makes all the difference.
As far as altitude is concerned, Norcold quietly changed the 1200 burner several years ago by adding a 4th mix hole, thats why they now sound like a jet and constantly pop (backfire). And I have never gotten them to admit that 4th hole is even there, they simply say they reserve the right to make changes. Anyway, the way to fix the pop, and quiet the damn thing down at sea level; I added a small SS hose clamp and slide it over the holes until the flame dejour is achieved. Higher altitudes? Go out and change the mix! Problem solved.
