Also, It's also not the seating capacity of the boat or number of spark plugs on the truck that's important, it's the combined weight of the boat, trailer, and the stuff you have aboard compared to the tow capacity of your vehicle. You also have to pay attention to the hitch and it's capacity. To give you some perspective, a typical jet ski on a trailer is about 800 lbs give or take. If your trailer has no brakes, that's about all your 720 is rated to handle safely. If your trailer has brakes, you could probably safely handle a pair of jetski's on one trailer. Hope that helps.
