Its mainly just gonna be on there when I feel like I might need it or when i know that ill need it to do some work with...Only for a few days at the time.... the roof rack idea was a thought but it just seemed like it would be a pain taking it off the roof all the time...with my luck I would drop it down the side...im also fairly tall and when i get out my head is at rack level...if i mounted it on the outside either me or a passenger could knock their head on it.,,plus when i go kayaking it would not allow me to put as many boats on top...my only other idea was to use a mount that goes into the trailer receiver..ive seen some on ebay..only prob would be a serious lack of clearance in the back and i would drag it on everything.
