I had National (above) put in a Amish cooling unit several years ago since I was in the area. I ran mine out of level and while it still worked, in hot weather it was marginal even with extra fans. Putting in a cooling unit is something you can do yourself and there are several video on doing it. I'm able to get my 1200 out by myself by having a platform almost as high as the bottom of the unit which I slide it onto. Remove the four bolts inside before laying down and then it's fairly simple to remove the old unit and put the new in.
I recently bought this spare
Refrigerator as it will fit where the 1200 was with only cutting out the top area where the screws go that hold the 1200 in. Most 20+ cu ft ones are 6" taller and require major modification. If I install this unit I will probably put in a seperate pure sine wave inverter to power it as I already have extra batteries.
