THE EPA CAME OUT WITH REQUIREMENTS IN 2013 THAT ALL DIESEL ENGINES HAVE A POLLUTION MITIGATING DEF (DIESEL EXHAUST FLUID) SYSTEM. APPARENTLY, THE EPA REQUIRED THE INDUSTRY TO MEASURE THE FOLLOWING THREE ITEMS WITH RESPECT TO BLUE DEF. - LEVEL OF DEF - TEMPERATURE OF DEF - QUALITY OF DEF I HAVE BEEN TOLD THAT THE EPA GRANTED AN EXTENSION OF THE THIRD REQUIREMENT, QUALITY OF DEF, SINCE NO ONE COULD MANUFACTURE THE EQUIPMENT NECESSARY TO DO SO.

This vehicle has fuel fill on both sides. You have to open the other side in order to prevent a vapor lock on the fueling side. I have fueled this way numerous times without incident. I recently fueled the same way and fuel gushed out the opposite side without tripping the fuel nozzle cut off. This resulted on a significant amount of fuel dumping on the fuel bay.

WHILE DRIVING ON THE INTERSTAE THE CARGO DOOR SKIN BLEW OFF. THE DOOR IS APPROXIMATELY 48' X 28" THIS COULD HAVE GONE THRU A WINDSHEILD AND CAUSED A FATAL ACIDENT. THIS HAS BEEN KNOWED THAT TIFFIN USED DEFECTIVE GLUE IN 2019' BUT THEY HAVE NOT MADE A RECALL, THEY HAVE CORRECTED SEVERAL OTHER VEHICLES BUT NOT ALL OF THEM MANUFACTURED WITH THE DEFECTIVE GLUE. THIS SHOULD BE A RECALL. THERE WAS NO WARNING OR ANYTHING VISIBLE TO US BEFORE DRIVING ON THE ROAD.

Our motorhome came with an optional electric grill that is mounted on a slide in the storage compartments. While underway, the slide deployed, popping open the compartment door. The slide was then hanging out approximately 5 feet while going down the road. Thankfully someone flagged us down just before we would have struck another vehicle with the slide. Upon further investigation, the slide that the grill is mounted on has a placard stating the slide is limited to 500 pounds total weight EVENLY DISTRIBUTED. The grill is mounted at one end of …

Frieghtliner uses a tire pressure monitoring system manufactured by Valor. The system is unreliable and stops transmitting data to the instrument panel without any notice to the driver. The only way you discover it is not working is by scrolling through options on the instrument panel and discovering that instead of registering pressure and temperatures, you have dashes displayed. There is no alarm or other indication the system has failed. Loss of air on a steer wheel in a large motor home is potentially life threatening. The loss of pressure…

I recently experienced a failure of the Dash A/C on the ref RV. After calling Freightliner, Savannah to find our if they serviced Dash A/C’s, which they informed me they did, I decided to have it inspected locally to rule out a quick fix like recharge the refrigerant. The Mobile RV Mechanic, whom I have used several times previously and is very competent, troubleshot the system and found that the A/C compressor was not engaging. He then found that there was only .2V to the compressor clutch plug. Suspecting the PDM, he called Freightliner T…

While driving the top bunk above the drivers and passenger seats came loose from the latches and came down blocking my view of the road. My wife just sat down in her seat otherwise it would have hit her on the head. She was able to guide me to the side of the road and it put the bunk back on the latches. This is a huge safety problem which blocks the view of the driver. and can cause a major or even a catastrophic accident I sent an email to Tiffin and their response several weeks ago was thanking me for letting them know. There was no f…
