So far I have carried my mini on the roof rack of my truck.Now that I have added a third ski to the axle the rig is a tad heavy.I am now thinking about alternatives so I don't have to lug it up and off the roof rack. I don't want to dismantle the mini to fit it inside the back of my truck.So I am now thinking about mounting it on the back of my truck on the tow ball in some way like a bike carrier.Has anyone played with this idea so I don't have to reinvent the wheel etc?
