This is regarding a 2023 Winnebago View 24D RV on a 2022 Mercedes Sprinter chassis. While attempting to back up an incline (transmission in reverse gear) the RV will not move. Engine revs up to only approximately 1800 rpm, but the RV remains stationary. Incline is our driveway, connecting to a parking area for the RV off to the side. Climbing hills with transmission in "Drive" is no problem. I took the RV to Mercedes Benz of Knoxville, Tenn., and they stated that they could not duplicate the issue, that the vehicle performs "as designed". They further stated that they had another vehicle in the shop for service and it performed in the same manner. I have no idea how steep an incline they tried, but our driveway is fairly steep. Gross Vehicle Weight Rating is 11,030 lbs. I had the RV weighed after loading it fully, and it totaled 10,725 lbs. No warnings appeared on the dash and no telltale symptoms. Mileage on the RV is 3150. Issue first appeared at approx. 2700, after I had the parking area built, so I can only assume the issue was present since new; I had never tried to back uphill before this. Backing up on level ground presents no problem. I tried calling MB technical support, but they only told me that I had to take it to a dealer; that they had no other options. I have a copy of the service order from Mercedes of Knoxville, but currently not able to scan. Will be able to at a later date.
