Re: Is 4wd needed in a truck to tow boat?
It depends... What's your definition of steep? Conditions of the ramp?
Most of the ramps I've used, I've been fine in two wheel drive even though my truck is equipped with 4x4. The ramps I use are well maintained, non-slimey, grooved concrete. There are a couple very steep ramps, I consider them almost vertical, that I haven't launched at but if I did, I'd be using 4x4 to launch and retrieve my boat.
This is with a 19'6" 305 powered Four Winns.
With that being said...I wouldn't even consider launching on a sand/gravel launch with my current setup without 4x4.
Depending on your location, you may want 4x4 in a truck during winter.
