First, congrats on your new Sunseeker and welcome to the FORUMS!! Hope you get your refrigerator working soon and that future trips are trouble free. Just to state the obvious, did you check all of your fuses? Also, there may be a fuse that you need to access from the outside. Open the outside cover and see if there is a small, square cover. Remove the cover and there should be a fuse mounted to the board under the cover.
Good luck and I hope that you get your problem solved quickly.
