I think a regular "dorm fridge" will be out of the question? (Looking for personal experiences given the explanation below...)
While I have a Yamaha EF2000iS generator, more often than not, the places we go don't have any elec hookups. More so, we usually setup base camp with the trailer, then go out on day long excursions. I don't want to leave the generator running (or out) while we're gone (I usually lock it up in the pickup). I haven't read much about how long a mini-fridge will stay cool without power, or how long/often I'd have to apply power from the gen to keep it sufficiently cool.
I've already got the computer fans and a couple switches. I've got some left over 1" and 3/4" foam board (with silver face) from a home insulation project. I figure I'll go ahead and insulate/install fans, reinstall burped fridge, and see how it goes.
Worst case scenario, the beer/water can go in the fridge and stay at 45-50, and we can put the perishables in the Yeti cooler for future trips. UNLESS, some of you can convince me that 30 mins or so of gen usage twice a day is sufficient to keep the fridge cool.
And yes Ed, I agree, any absorption replacement is out of the question. RM2510 is listed as the replacement, and they go for $675 at our dealer here in town, plus $75 freight. That'd be nearly half of what we paid for the trailer in the first place. And the 2510 isn't exactly a plug and play... I'd have to do some trimming on the opening. Not that I wouldn't with a residential fridge either (or fabricating trim pieces).
To the other poster, I was getting 11" water column at the valve when I tested it prior to winterizing. I'll clean the burner and jet too, but I've got a nice pretty blue flame right now. Probably about 1.5" tall.
