Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Tiffin sent out an addendum to be added to Owner's Manuals that states, "Tiffin Motorhomes recommends that all diesel units be refueled using standard automotive-grade diesel fuel pumps, rather than high-flow commercial truck stop pumps. The fuel delivery rate from commercial truck stop pumps is often too aggressive for motorhome fuel systems, which are not designed to handle rapid fuel intake. Using high-flow commercial truck stop pumps can result in overflow, spillage, premature shutoff, or even damage to the fuel fill components."

Service Bulletin/Repair Instructions
It has come to our attention that on certain Tiffin motorhomes equipped with optional Go Power! solar panel solar panels systems, the 30A inline fuse located before the cable entry plate should be removed. The plastic housing surrounding the fuse may become heat damaged from heat generated by the normal operation of the 30A fuse, which would cause the solar panel system to not operate as designed. Due to updated recommendations from Go Power!, Tiffin Motorhomes is removing this 30A fuse from the solar panel system.
