Why do you need to replace it? Failed cooling unit? (about the only reason to replace less it's falling apart and I rebuilt the fell apart stuff on my Dometic)
My cooling unit has failed after 14.5 years.. New cooling unit (Just the 'Back' side of the fridge0 is 665 +S&H (Single wide double wide's are more expensive) plus install CW tells me 4 hours. I don't think so.. That's still cheaper than a residential and a 5 year warranty.
Home was where I park it. but alas the.
