Jim at Source Engineering in Veneta Or. Took a fair amount of his time to give me the history on the Electronic shocks.
1) Monaco adapted them from Jaguar but did not want to spend the money to engineer them to the Beaver coaches.
2) After Monaco failed, Source Engineering Had all the specs and Engineering done for Beavers and Monaco and developed a shock to replace the electronic ones.
3) We looked into replacing ours because we were told they all needed replacement but replacing one broken shock worked fine. Jim has a few good spare electronic shocks.
4) Jim and Scott checked our whole system including the controlers and accelerometers. Works great! Very reasonable price as well.
