Some of you guys are talking about a 311 formula as if its some tiny single engine boat. 1/2 ton? That 311 full of fuel on a triple axle steel trailer is gonna be 10k lbs all day. Last I checked, 10k lbs is a substantially heavy load for any pickup. Add weight of the truck itself, and the trailer, your talking 15-17k lbs. Half tons have small brakes, suspensions designed to haul a few sheets of drywall and give the wife a comfy un-truck like ride.
Hell, I could sell my dually and hook up my girls hemi grand Cherokee to the boat. It is rated for 8800 lbs I think the manual says. Plus it has a hemi, and its srw. Should get great traction with those skinny 225 tires, lots of psi per square inch. I should be good as long as the jeep is maintained and tire psi set to 44psi. Then I could hit the bank drive thru, car wash, mcdonald's for a quick mcflurry on the way to the launch ramp.
