I've got a Dodge Dakota p/u with a bedliner and a topper. I'd like to get some sort of a rack for it; last year I was laying my bike down without any problems except for the huge waste of space inside . I guess it would have to be a fork mount, and the seat post would of course have to be lowered. I'd rather not use a hitch mount rack because I'd like to lock everything inside. A lot of the racks I see for trucks are great, but they are for open trucks, a little high for a cap. Anybody have any preferences or suggestions? Thanks.
