As silly as this new product may seem to some, I personally think that Sea Sucker has potential. Not necessarily as a mount for a Hi-Lift or lights, although, the battery pack they offer to power one up is novel, where I see it working out well is for things like a bike rack or even a roof rack - this, assuming you have a painted hard top or bed cap. Anyway, there are a lot of professional camera and film gear that uses suctions like this and so, I thought it was worth a mention.
