A lot of commenters saying you "need" a trailer (instead of an F150), but another option would be one bike in the bed and the second bike (if needed) on a hitch-mounted rack. A hitch rack takes less space to store when you're not using it than a full trailer. It would probably be more annoying to load and unload than just putting two bikes in the bed.

Anyway, if you want an F150, get it -- I don't really care.
