The Freightliner Chassis Owners Club (FCOC) costs $15 annually. I signed up right there in Gaffney when they were working on my rig and they still applied the discount. You can give them a call at 864-487-1700
I also enrolled in the Cummins discount plan. I believe that was $20 annually and provided a 10% discount, which on the $7,000 for a fuel pump and labor charges saved me about $650. The enrollment brochures were on the counter of the service department and the service manager assured me if I completed the form and paid my $20 they'd apply the discount when the final bill was prepared, which they did. Sorry about your motorhome issues! The dogs and I are in SUNNY Florida, so I haven't had the benefit of the daily rainfall.
