I have previously posted my poor luck with a Norcold 4 door that I ordered in my 2014 Lifestyle fiver. BIG MISATKE and waste of money. After a year of poor performance in inconsistency and no satisfaction from Norcold we pulled it out and replaced it with a Samsung residential. Best RV mod I have ever done! We do not dry camp so power is not an issue. The 2 6 volt batteries and inverter pre-cool it just fine with power to spare for in route travel and cooling. Do yourself a favor and get the residential. You'll love it.
