Some Thoughts for your towing needs.
1.) I have never been in a situation where I wished I had less power, either on a boat or tow vehicle. If you get a truck that struggles, your stuck with it unless you go thru the hassle of trading it, etc.
2.) Things change. You may find your Horizons expand, you want to take the boat to different destinations, anything can happen in Life. If you buy a truck that will easily haul the boat anywhere, you're that much ahead for your next Chapter.
3.) If you purchase a trailer, please don't listen to someone who wants to sell you a trailer that's undersized for your boat or right at capacity. This is a mistake. Your trailer should have at least a 2000-3000 lb cushion, or you'll blow bearings prematurely, welds break over time, and in one case (mine) the axle actually bowed from the weight of my Seafarer, screwing up the camber and wore my tires out in a few hundred miles before I realized what was happening.
In writing, (or typing, I guess,) I'm planning so you can take that boat anywhere. If your positive you'll just trailer short distances, you can cut corners. besides, it's easier for me to spend your money than mine..
One last observation; LuckyDude is right about having 4WD. You don't need it 'till you need it, but when you do....
