Should I join Good Sam?

I can't give you a real clear answer. For us personally, the club membership doesn't seem to pay off much. Partly that's because we use public campgrounds most of the time. Also, seems to me that many private campgrounds are looking for a reason to give you a discount and will give one for various reasons even if you don't have Good Sam. Possibly I've missed some other discounts but not aware of it. As far as the road service, also can't give a raving endorsement. When we blew a tire on the MH, they did get us road service but said they could not locate our tire size anywhere around, while there was a tire shop less than 5 miles that had one. When our tow bar became disconnected they suggested we call the Police, which was appropriate, but then they never called back to see if we got what we needed.
