Shouldnt be a problem for the 1500 to pull a 23 - 25 ft boat.
I did all the time with my 25 wellcraft with a 2 wheel drive Ford F-150 w/ the 5.4L.. not a problem or ramp issue at all.
Anything over that... I'd consider movin up in truck size to at least the 2500 series or F-250 series truck
With a boat that size,, the back tires of the truck should never hit the water no matter what grade the ramp. As long as you dont spin the tires, put it in low 1 and slow roll the boat on out... I've done that with both the Dodge 5.9L and the Ford 5.4L (both 2wd's) and with a 7,000 lb load on the hook. Dually would be over-kill unless you need to pull out a 10K or larger sized boat.
