I know that there are very diverse opinions on tow vehicles, especially with front wheel drive vehicles. You're right that modern day 6 cylinder engines are pushing 300 horsepower, and that's enough power to pull a 4,000 lb. or 5,000 lb. load. There are other considerations.
My Lexus RX SUV has a very strong frame, and it's very structurally sound. But, the brakes are out of a Camry and I'm hesitant to think it has the stopping power for a 4,500 lb. vehicle, 1,000 lbs. of occupants and a 4,500 lb. pontoon boat and trailer. A good crosswind on a pontoon boat could destabilize a tow vehicle with such a short wheelbase. The front wheel drive axles have constant velocity joints on each end, and they're very small in diameter--and structurally weak. When 500 lbs. tongue weight is applied to the back end of my RX, the front end becomes light. Turning while pulling a trailer doesn't mean my RX has enough weight on the front end to make the turn. Since 2/3 of braking comes from the front wheels, an emergency stop wouldn't be pretty--and the short wheelbase under heavy braking could add serious control issues. There's not enough cooling capacity in my "Camry" transmission for towing, and heat could make my tranny prematurely fail. On a boat ramp, much of the weight of the tow vehicle transfers to the rear axle, which takes even more weight off an already light front end. Spinning front tires could be dangerous to others on boat ramps--especially the steeper ramps. With 5 people on board, my RX is already fully loaded and max'd out weight wise without adding a 4,500 lb. boat behind it.
Safety of the occupants, safety of the boat and long life of the tow vehicle are up the utmost importance. While some FWD SUV's seem to tow okay, you really don't want to get into an emergency stopping situation or even worse a jack knife situation in a vehicle that wasn't designed for such weight. (I've been in that position.)
A 1/2 ton V-8 pickup truck or SUV is still the preferable and safest tow vehicle for pulling these boats. Every family needs a pickup truck, even if it's an old one--just to haul around all their stuff.
