All things considered, you may want to ponder driving the 730 miles from Salida CO to Tucson AZ and have the guy there do the whole job. The warranty is the same as going with a new unit, but I believe that the cost will be much less. As I said, they replaced the fridge in my friend's 5th wheel and he was most satisfied with the job. Because they rebuild all the cooling units, they meticulously inspect the welds (better QC than Dometic's factory). As well, they made my friend stay for a few hours to ensure that the unit worked properly.
I recall them setting up an appointment for the work to commence at 8:00am.
