I will echo Cbones comments. We have a short super C on a freightliner for that very reason. Hubby figured you can find a freightliner mechanic just about anywhere and he has a thing for diesels.
. Some Dynamax models have a cab over option, ours does not. Renegade also makes a nice super c. Holland Motorhomes in Holland Michigan has a nice website, they market both manufacturers I think. The Dynamax website is really nice too with all the standard floor plans. The thing I really like about the super c actually is the truck-type cab. We both have our own doors! I know that may sound a little silly, but we haven't been in an A were we both had door. Since I don't drive the rig, I was always sitting 2 ft behind my husband with my feet dangling in the stairwell of an A.
