SO the thought here is it's OK to tow a boat as long as the truck doesn't need to touch the water? That doesn't make sense to me, I would want to tow my Jones Brothers 23 CF with my R1T. If that is not an option I need to rethink things.
As others have said it depends on the ramp which can also be driven by the tidal exchange (we have 8' new/full moon tidal shifts) and the type of trailer. There are many ramps where you are just going to need to get your truck wet some to get the boat in the water.
