Probably have to call around some more, in our yellow pages there are several pages of appliance repair companies, bound to be one willing to come out. There are mobile RV techs that have knowledge of residential fridge repair, worse comes to worse might have to take the rig to a RV service shop if all else fails. Hopefully you can still enjoy your current trip, maybe go old school and use a cooler to get by. I know in our 3 decades of RVing we have had to resort to doing this when our fridges went on the fritz. Good Luck!!!
