Great West Van on ProMaster at Tampa RV Show

i agree with the above on the Service Bulletin issue. As noted, unless it is safety related you have to ask and dig to figure out if your rig could benefit. We had a situation with our Tacoma where i found out there was a voluntary at-dealer-cost fix for the rear suspension. If you brought your rig into a dealer a simply stated that the rear end sagged under load you would get a free 4th leaf. So the lesson is, find a good forum for your rig and monitor weather there are fixes available and go for it
