If the A/C needs replacing DO NOT replace with a Coleman unit, they do not work as good as the Dometic, plus the filter can not be washed while the unit is running or the inside fins cleaned with a vacuum cleaner the evaporator fins are inaccessible.
The worst part of the Coleman units is that it does not cool after the temps outside reach 80 or more, after that is just makes noise and the temps inside go up, the Dometic we had would keep the rig cold in 120+ with no sweat, with the Coleman the inside temp stays at 80 to 95 depending on the outside temperature.
Please do not tell me how good the Coleman's are, we had a Dometic that lasted 15 years, now we have the Coleman, same hot dessert, big difference.
No we did not purchase it, insurance repair, el cheapo.
