For what it;s worth ... I use 4WD, Low pulling my boat (about 3000 lbs inc
trailer) up all ramps including muddy bottom and gravel. Just put it in gear
and it will idle it's way up, no tire spinning if necessary ... then it's
back to 2WD. This is with a 3100 lb or so '96 Jeep Cherokee which is
probably lighter than your truck. My opinion, you'll eventually have
traction problems ... but maybe as mentioned, a wheel on the trailer tongue,
and some good rope/tow strap, and/or a come along or winch ...

We can talk about any sizes, specifically the 16' and under I'm interested
in.... My truck is 2 wheel drive standard with a light back end... my boat
launch areas include:
1. beach with grassy incline to follow
2. an older gravel boat launch that could have a tiny bit of muck just
near
the water.

My biggest thoughts are around the rear wheels spinning coming out of the
water with the boat on... then getting stuck...
