So. . .if you are loading just one boat which side do you put the Hullavator on? I see it both ways: 1. Put it on the driver's side so that the boat isn't over-weighted on the "downhill" side of the road camber. This is why you load a horse on the driver's side of the horse trailer (if you are only loading one horse into a horse trailer). But of course, a horse weighs a lot more than kayaks.... 2. Put it on the passenger's side so that the boat isn't in danger when trucks pass on the left. Which is best?
