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.

Tiffin will verify attachment of the front cap to the chassis cab and update the sealant.

To correct this, a new wire harness will be installed at the same time a programming update is competed so that the backup camera and rear signal lights will function as designed.

Notice applies to engine. Engine is equipped with an Engine Control Module (ECM) that may have a manufacturing defect that could result in as engine stall without warning. An unexpected engine stall without the ability to restart the engine may lead to an increased risk of a crash. Cummins has released Safety Campaign ECM. #C2614 CM2450 ECM Replacement Safety Campaign to address this condition by replacing the ECM.

defect that exists on specific model year 2017 - 2022 Freightliner Custom Chassis X-Line chassis manufactured February 20, 2017 through November 18, 2021 that are equipped with a valve stem extension and stabilizer configured with a specific tire valve stem and wheel combination. Tiffin Motorhomes built motorhomes on these specific Freightliner chassis between April, 2017 through December 6, 2021. Certain chassis may have been built with the tire valve stem extension for the inner wheel contacting the outer wheel rim opening, potentially damaging the valve stem resulting in a loss of air pressure in the inner tire. A loss of air pressure in the inner tire on a motorhome with a single drive axle may overload the outer tire and increase the risk of a crash.

This could lead to a loss of steering response and a lack of direction control, increasing the risk of a crash. The driver may experience some additional free-play in the steering and/or feel an improper steering alignment.

Replaced with these, but these new lights have to be wired in instead of just clicking in. These are the instructions to wire in.

This can cause the wipers to fail, reducing the drivers visibility, and increasing the risk of crash.
