I have a 2007 Contessa Bayshore 42 ft, C-9. I am having some paint work done and want to keep the refer functioning during the process. While in the paint booth, can I put the refer (Dometic NDA 1402 autodefrost) in AC mode and plug the refer power cord and ice maker power cord directly into a 110 outlet? Each night, the coach will be backed out of the paint booth and plugged into 50amp service.
