The corporation that owns Camping World bought Good Sam awhile back. They publish a magazine and have insurance and other items. They give a discount for items you purchase at Camping World however I purchase from RV Parts, RV Accessories RV Supplies Priced Low
and off Ebay and get better deals. One of the good things about Good Sam is they have an Action Line where you write describing how you got ripped off and they write a letter and publish the findings in their magazine. They tell you who did the ripping and what the outcome is. It's surprising how many prominent companies wind up on that Action Line.
There are thousands of Good Sam members around the country and that is who a person should call to get help on selecting a maintenance provider. You are never alone with Good Sam.
