I have a 2003 Marlin with 4.2l Yamaha 300's on a triple axle aluminum I-beam trailer. With full tanks of fuel, including the weight of my truck with a full tank of fuel, the scale weight was 21,940lbs. The very next day I did a dump run and the truck weighed in at 8,540lbs on the way out, and of you want to get picky you could add in 10 lbs of fuel burnt from the day before so lets say 8,550lbs. This puts the boat and trailer at 13,390lbs. I plan on weighing the trailer empty but I'm guessing the trailer is somewhere around 3,000 give or take a couple hundred, so I'm pretty confident the boat weighs in at around 10,000lbs give or take a 500lbs.
I tow with a 2017 Ram 2500 Cummins and my trailer has surge brakes. It could use airbags and I do plan on upgrading to electric over hydraulic brakes at some point but it's totally fine. That being said I've been towing large boats more or less for a living for the last 8 years so my interpretation of "fine" may be different than others. Poeple get too caught up trying to do the speed limit or more while towing heavy, Any large truck will slow down over even moderate elevation change with this kind of weight and if you want your truck to last you shouldn't be pushing it that hard. I used to tow a 17k lb boat from Western Washington to Montana (6 major mountain passes depending on the route) on the regular with either an F550 or an f650 with a QSB Cummins and after awhile I just accepted that the truck performed the best doing 60.
For what it's worth in my experience any newer diesel 3/4 ton will have a drivetrain capable of towing that boat, it's all about how the suspension loads out. I will say that our truck does have the factory rear coil springs and four link set up and it does do some weird things on really uneven roads, I think a leaf spring truck might track a little straighter, but again I have no problem hauling it around.
