We've owned Ford class C's and B's of the 1980's in the past and at present have a 21' 2004 R-Vision B+ along with our lass A Tiffin. When we purchased the B+ for a trip to Alaska, my wife insisted on a Chevrolet 3500 Chassis, due to leg room on the passenger side, I felt at the time it didn't make any difference. She's 5' and I'm 6'-2" tall. After renting a 20' Ford F450 Penske box van for a 1500 mile move to Florida, in which she did 90% of the driving due to me wrenching my leg, I wouldn't have the current Ford RV Chassis, way to tight for leg room for me. This was after traveling in our B+ towing a 14' trailer, a month before over the route, again with here doing most of the driving after the 1st day.
