I have a 2013 35 foot gas Fleetwood Bounder with a V10 Ford engine. While in cruise control, even a small hill or overpass will cause the trany to downshift to a lower gear, causing the engine to rev...

There are several things that I have found that help this downshifting problem not mentioned yet. When I first bought my MH 10 years ago it downshifted at the slightest hill. Headers,a FF muffler and CA intake cured that problem. After several trips out west and to Alaska larger mountains would cause a lot of downshifting. I had an old vacuum gauge in my garage that I installed and it made a world of difference not only in shift points but in a slight mpg gain. When I see a hill coming I increase my speed before the hill once the MH is climbing and RPM's begin to drop I let off of the gas and maintain 2 psi of vacuum on the gauge this will keep the MH from downshifting. Off course on very long steep hills where you need more power I let it downshift.
