Thank you all for the responses. We have a Coleman popup right now but are outgrowing it. When we got it I had to essentially do a compete roof rebuild and piles of other maintenance. I don't care to do the roof rebuild again, particularly in a travel trailer, but it definitely gave me an appreciation for the damage water intrusion can do.
As for the fridge, would a stock fridge from am older model like this one typically still run in the $1000-$1400 range? Assuming there's no ammonia leak, I would think anything else could be repaired? I have a small LP/DC fridge in our popup and am familiar with maintenance of it. I'd think this one may be similar, but on a larger scale?
