black, fwiw, I started out with a launch20ssv(much smaller than the mojo) and had a '99 ranger 4x4. I only towed to the ramp 2x and sold the truck(15mile tow one way). granted it had the 3.0, not the 4.0 so it was a dog going up the hills but the boat really pushed the truck around when you tried to stop and it just didn't feel "right". With a lighter boat like the obv, I'd say try it, but that mojo and a small suv are a recipe for a mess. Granted the truck doesn't owe you anything but it's worth a lot more now to upgrade than dead on the side of the road with melted brakes or a tranny that grenaded everywhere
don't forget trailer, and more importantly beer in your calculations....

oh and congrats on the new boat. you are going to love it... sounds like a steal on the surf engine..
