You'll have room to spare if its an 8' box. Just be sure to tether it from moving forwards or backwards even though the gate is up or you'll be replacing a back window.
I used some 1x8 plank to build a partition that fits in the slots of the bed liner. It keeps the bike from hitting the window when loading. Also works great to keep gas cans and other small items from rolling around in the bed.get a louisiana guard dog. it'll hold your bike and keep it from going anywhere. you'll only have to worry about the rear window when pulling into you truck.
