I once owned a 3000# Grady White 20 Overnighter. I trailered it with my 1987 Bronco II which had the 6000# towing package upgrade. The Bronco II was four wheel drive, which I engaged to launch, and especially recover, the boat. If you find yourself on a wet, steep ramp with algal growth, and especially if the rear wheels are even slightly in the water, you should anticipate possible loss of rear wheel traction and maybe even slide further down the ramp trying to recover.

A “monster truck” with big wheels/tires might or might not be needed to launch and recover safely, depending. But 4WD is a blessing to have for that kind of work at anytime. Engage the 4WD in lowest gear and just let the truck crawl up the ramp!
The “hassle factor” for what you plan is quite high.
