RV fridges, maintenance, etc.
Your best bet is to find the Dometic web site, and/or go to a REPUTABLE RV appliance dealer that knows his/her stuff.
There is more than ammonia in RV fridges; there's chemicals that promote the operation and reduce corrosion. These can PERMANENTLY screw up the small passages if the fridge is operated out-of-level, so set the bus level before mounting, then level the unit in the level bus.
Also get the special long brush to clean out the flue once a year (at LEAST) so soot and dust doesn't reduce the fridge's capacity for cooling.
My fridge came out of an '85 fifth-wheeler, and still runs strong. Just keep it clean and maintained.
The tool storage is nice, but where do I put the bed?
