Stopped by Carter's today. They are still in business as an RV repair shop and consignment sales. I talked with John Jr. and he said the repair business keeps them jumping. They also do RV repair house calls. They have one TM on the lot for repairs (needs a fridge). John said there is a back order list for both the Norcold and Dometic in the size used in the TM.
I didn't recognize any of the maintenance techs on the grounds today. I talked with 2 of them. One has been with Carter's for 5-6 months, The other said he had been around since the TM's first arrived at Carter's - he isn't old enough! Question is, can they fix TM specific issues?
For those interested: There is a 2003 2720 on consignment at Carter's. Contact info is posted earlier in this thread.
