Hey i have a ford explorer, i was thinking about getting a 12ft jon boat and sticking it out of the back window through the whole car with the seats down. My question is will it fit if i strap it down? when i had a pick up truck i would strap down a 17ft canoe with the tailgate down and have it lay on the roof of the truck. It seems like i could do the jon boat with the explorer, but im not going to buy one it i cant fit it where i want it. thanks.
