For what's it worth. We have RV roadside assistance. We used it once..and it didn't work. We bought the plan in British Columbia when we bought the trailer..The service provider call centre was in Edmonton Alberta. We were 1/2 way between Walla Walla Washington ans Elgin Oregon when we had a flat tire on our trailer.
We also had the wrong cell service provider. Long story short after we finally got ahold of the call centre....they wanted us to contact a tow truck tire company and pay them for the service then send them the receipt.
A very nice truck logger stopped and patched the tire and we were off. Stopped at Les Shwab in Walla Walla....they redid the patch no charge...just great.
We now have BCAA...similar to AAA.
