The electric step on our coach broken on the road with the gear box issue and get loose , it is very dangerous to run with the electric step open to get people injured and also for the people that disembarked from the motor home, we feel that electrical step should have a safety when it is close .

UPON PURCHASING THIS 2021 TIFFIN PHAETON RV, I REALIZED THE "A PILLARS" CAUSED MIRROR AND VISUAL OBSTRUCTION. INITIALLY BELIEVING IT WAS A MIRROR ADJUSTMENT, I LEARNED THAT THE DRIVER SEAT WAS NOT CENTERED ON THE STEERING WHEEL / DASHBOARD AND IT WAS POSITIONED TO THE LEFT APPROX. 2"-3". NOT ONLY DOES THIS PREVENT A CLEAR VIEW TO THE MIRRORS, BUT IT CAUSES "PEDAL CONFUSION" AND COULD RESULT IN A CATASTROPHIC COLLISION RESULTING IN A FATAL(S) THE DISTANCE BETWEEN THE GAS AND BRAKE PEDALS ARE APPROX. 3". HAVING THE DRIVER NOT CENTERED ON THE STEERING WHEEL AND STEERING COLUMN CREATES SEVERAL SAFETY ISSUES. WHEN SPEAKING WITH TIFFIN REPRESENTATIVE (JEREMY NEWELL), HE STATED THE DRIVER SEAT POSITION WAS AN ISSUE IN 2020 AND THEY MANUFACTURED A BASE PLATE TO SHIFT THE SEAT OVER TO CENTER IT ON THE STEERING WHEEL AND DASHBOARD. THIS ALSO POSITIONED THE DRIVER SEAT CORRECTLY OVER THE GAS AND BRAKE PEDALS THUS PREVENTING "PEDAL CONFUSION". GREG DEES (REGIONAL DIRECTOR) AT TIFFIN ADVISED NHTSA HAS APPROVED THIS SEATED POSITION AND THAT THE "LEGAL TEAM" AT TIFFIN ADVISED THEY SHOULD NOT MANUFACTURE A NEW SEAT BASEPLATE TO CORRECT THE ISSUE BECAUSE IT COULD COMPROMISE THE SAFETY OF THE DRIVER. I ADVISED DEES THEY DID THIS FOR 2020 RV'S AND ASKED WHY WOULDN'T THEY CORRECT THE ISSUE IN MANUFACTURING FOR THE 2021 RV'S? DEES ADMITTED THEY HAVE HAD SIMILAR ISSUES, BUT FOR SOME REASON WON'T ADDRESS THE 2021 RV BECAUSE THEY USED A NEW MANUFACTURE FOR THE SEAT POST ("VILLA") INSTEAD OF FREIGHTLINER. I HAVE EXPRESSED MY CONCERNS WITH TIFFIN WITHOUT ANY SATISFACTION AND AM NOW SEEKING THE ASSISTANCE FROM NHTSA AS WELL AS THE FTC. IT DOESN'T SEEM RIGHT THAT THIS ISSUE SHOULD EVEN MAKE IT THROUGH AN INSPECTION UPON COMING OFF THE MANUFACTURE LINE. I AM ALSO CONCERNED FOR EVERY OTHER 2021 TIFFIN OWNER. I HAVE INCLUDED 5 PHOTOS USING A STEEL RULER.
