Is anyone familiar with this company? They sell air actuated extendable masts that extend to 30 feet and collapse to 3 feet. This would be perfect for a mobile mast mounted on the back of my sleeper for a beam. Here is the link. http://www.clarkmasts-usa.com/QTM.html
The only problem is that they are located in the UK and I know shipping will probably be just as expensive as the mast itself. Is there anyone in the US that sells the same kind of item? I am working on a beam that will lie flat against the back of my sleeper and with a motorized head, rotate it into place once it is hoisted up into place. A "V" beam made out of hamsticks seems like the way to go on this. Any and all comments are welcome.
