It's safe to say that Dometic today is not the Dometic of years past, as is true for most all manufacturers. Our 2015 model trailer was brand new when we got it and the AC was giving problems from day one. All the band aid fixes were done to it and the final fix was me throwing it off the roof. After much research, and seeing how many people online are saying their new in box replacement Dometic ACs we're failing, even on Class As I went with a Australia DESIGNED and BUILT air conditioner. Of course Dometic bought the company out and may kill off the brand but so far they have not touched the ACs or cheapened them out.
