Our coach has a 1200 Norcold and we are full timing with no problem. Friends been full timing for over 10 years with a 1200 and just had a new cooling unit installed after over 10 years constant use!!!! Agree with dougrainer on the people who bash Norcold since Dometic has had just as many problems but the difference is Norcold did step up but fell short of replacing cooling units but why change them all when it was found only a few had problems. Any thing that runs off gas/propane can catch fire. How many of you regularly clean the vent stack on you fridge, furnace or water heater!!!
