I'm a bit skeptical about hauling that distance with a pick-up truck. With trailer and typical load of cruising gear, I would guess you're talking about close to 20K pounds. That's a mighty load for a pick-up. But maybe with a dual axle?
Not sure what time of year you plan to do this, but if it's in the autumn/winter/early spring, remember that you will have to fully winterize the boat for the trek across country.
Good luck! BC sounds like a beautiful place to settle.
