I read countless comments that the Sprinter cab is the most comfortable compared to the Ford E-Series and Chevy, and I agree. When sitting in a Sprinter cab at auto shows, they just feel better. It would be real nice if our E350 driver foot well offered more room side-to-side, but the big V10 engine needs the space. Not only is the foot well tight, but the gas & brake pedals are skewed to one side. At the same time, I cannot say our E350 is uncomfortable. We all adapt. But when shopping around, those things are easily noticed.
About driver seat travel, forward and backward. Regardless of the chassis, I think the design of the motor home is most influential, primarily the transition wall between the steel front cab and the fiberglass sides of the motor home.
If the transition wall is at an odd angle as shown here, this places the slide out further back which provides a lot of space for the driver & passenger seats to travel back and recline.
If the transition wall is at a right angle, this moves the slide out much closer to the driver seat as shown here. This is where you can have limitations with seat adjustment.
About the Sprinter Duel Rear Wheel Axle Design....
The narrow dual rear wheel axle of the Sprinter moves the pairs of rear tires closer together. This narrow stance is very Euro-friendly for their old world narrow road systems. But here in the USA where roads are much wider, a wider stance makes more sense for better stability. Yet Sprinter owners claim the narrow stance does not have stability issues which is good to hear so.
It is all about give here, take there. There is no clear winner for every type of motor home. We are being a bit hard on the Sprinter chassis in this thread, bringing out concerns over it. But every choice has issues of one kind or another.
If I were to scream loud over any chassis at all, it would be the new Promaster where the rear axle comes only with single rear tires. Now that is a real
RED FLAG to me. By it's very nature, it is less-stable, under-rated, and over-loaded. They might be okay if traveling alone and light. But two adults and all their stuff quickly over-loads the chassis and it's single tires in back. I don't know how the RV industry can legally offer a Promaster motor home. They appear to have "LAW SUIT" written all over them, not so different from the late 70's early 80's Toyota C&C pickup truck chassis days.
Here is the Promaster chassis. It comes one way, with single rear tires. That is too much to ask for a typical motor home application.
