Hi pac1977, have you picked up your new toy? I'm very close to making the jump on a 17.58-3 ob and being 6'3" have similar concerns about the bed size. I am in two minds as to whether or not I should modify it myself as I think it would be good to still have the shelf. I spoke to a couple of dealers and had mixed opinions on whether jayco had a solution. I would love to see a photo of what the factory comes up with prior to making a decision. Hope your happy with the new van when you get it, seems like there's plenty on here that would appreciate any feedback. Cheers.
