Jeff, I used a Chev S-10, 2 wheel drive for my M17 launch duties with no issues. It will make a huge difference what the ramp bed consists of. Is it a concrete apron or mud and sand?It also helps to pull out with the auto transmission in 2nd gear, not low. I think you'll be fine, the M15 is half the weight of the M17. You can always throw a length of chain and a come-along in the truck for security!
