Air conditioner replacement

[jcurtis934]

After 10 plus years, our rear ac is going the way of the dodo. Our 3800RE was built mid 2012 and titled as a 2013. The rear ac is a dometic 541816A701C0. We think we need to replace it with a dometic brisk air 2 ducted unit 15k btu, but would love to hear input on if this will work in our unit, etc. Thanks, john
