I am on my second 21'. I ordered it that way. Makes a big difference when turning, especially with a 32' motorhome. I love it, and everyting fits. I used to carry my quad and it was fine, but I carry a pit bike and bicycle. Has move then enough room with my 69 Valiant, or 71 Dart.I also have a 2' bench up front.
Bottom line, I like 21' way better.
