This Sporty worked well, but without an inner cooler for the 7.3, I worried a bit about the long haul.
Decided to go for a dedicated tow vehicle that has worked much better:
Even with a big pickup, the boat still pushes it in a panic stop situation. Hit a deer a couple weeks back. Truck by itself would have stopped in time, but the boat, even with the brakes working correctly, kept the truck motoring down the road for quite a bit. I can't image how great the stopping distance with lighter pickups and SUVs, so that's something to consider when shopping for a tow rig.
