Hey Ozz...
In our rig, the central location is under the tv cabinet. The vacuum outlet will be almost dead center fore and aft.
I just went out and finished my layout, and will need to use an extension hose between the outlet and the vacuum. In order to keep the bend in that hose from being too sharp, I had to lay the unit on the floor across the rear of the cabinet. Since the unit has a bar across the side on the floor for mounting brackets, I made up some dense foam spacers (three layers with a groove in the middle).
This got me thinking (more trouble
), this unit makes a LOT of noise...maybe I can mount this without screws direct to the trailer. It'll be sitting on dense foam already, and I can use some TV Super Grips to hold it in place. I just happen to have a few on hand...
Of course it's cold out here, so we'll see how that goes. Adhesives don't do well in the cold.
Tomorrow I'll pull out the roto zip (where'd I put it now)...and I'll take a couple pics just to show my idea.
