I would select a tow vehicle that out weighed the boat, motor and trailer, And look very closely a adding brakes to the trailer. That said most any full size pick-up with a V—8 would suffice as a tow vehicle.
On April 7, 1988 I was ran off the road and rolled a truck with a boat in tow. I rolled five times, Why? I was pulling a 18 foot Skeeter 175 Starfire, loaded out with a 175 Mercury, trolling motor, 28 gallons of gas, three full size batteries, mine and my buddy’s fishing gear. I was towing with a Toyota extras cab 4x4 pickup. The boat, motor and trailer weighed more than the tow vehicle. The accident darn near killed both of us, I had just stopped at a fast food place and got a milk shake and hamburger, when we got back in the truck neither of us put our seat belts on, we bounced around quite a bit in the roll and has milk shake and hamburger all over us.
After the other driver’s insurance paid off I bought a new full size Ford pickup and when I went to buy a new fishing rig the first thing we talked about was trailer, I ordered a tandem axel trailer with four wheel disk brakes, it was costly but had I been equipped in this manner when the accident occurred I would have likely been able to prevent the roll.
To me the first thing I would ask is, “can I stop the rig in an emergency?”
A cop witnessed the accident, when we stopped rolling I was pinned in between the roof and steering wheel, the driver's side door would not open. As the cop came up to the vehicle he asked, "are you alright?" I answered, "Yes, just gt me out so I can shoot the crazy dude that ran me off the road." The cop turned to my buddy who was out of the vehicle and asked him, "Does he have a gun/? My buddy told him, "Yes, he doesn't leave home without one." After being told that the cop would not get me out untill they found and unloaded my pistol.
