I was in the same boat you are, pun intended. I have a 2014 GMC Terrain with a 4 cylinder I was towing a 19' boat with, it towed it okay. I think the boats around 3,000 lbs. with the trailer and my trailing max on that vehicle is around 1500 lbs. or 3,500 with a 6 cylinder. Anyway, I installed trailer brakes because that was my main concern, stopping. I still didn't feel comfortable towing the boat with a 4 cylinder, I didn't want to ruin the engine or trans. and the Terrain only has about 12,000 mile on it. I bought a 2003 Ram 1500 last October with a standard cab short bed(which I prefer) with 4WD that has a 4.7 with a 3.92 axle ratio and 66,000 miles on it. I haven't towed the boat yet, but I'm sure it will have enough power to tow it. I would have preferred a Hemi but I got a decent deal on the truck and it's in nice condition for it's age and has low mileage. I did want 4WD for slippery ramps, just to play safe.
