I have to truck a new to me bike. The only trucks available are crew cabs with short beds. From what I see online the short beds are 62" long, not sure how far a downed tailgate will extend this. The bike has a 57" wheelbase with 18" wheels. If I use that wheelbase plus half front wheel diameter (9") it's 66", not counting front tire thickest. If ya add 3" for tire it totals 69". Question is, will rear tire patch be sitting securely on tailgate? This is on paper as I have neither the truck or bike yet to take measurements. So, any real time experience out there with this size bike in a "short" bed? Thanks
