Don't take it to Camping World. Find a local RV tech. Or if you are up for a road trip, call Leon at
National RV RefrigerationHe's a young Amish man in Shipshewana who repairs and rebuilds gas absorption refers. He's the best we've ever found and you can trust what he tells you. You will leave a message and then he will call you back the same day. His website has some troubleshooting tips to try first.
He will not cheat you and he fixes things right the first time. He does have space to park a few rigs. We take our 40' Phaeton in there.
