I realize this is a tough one to answer.
But, I'm hoping somone weighed theirs before assembly.
The reason for my madness, is I want to use window lift motors to raise my galley lid, with just a push of the button.
My other hair-brain scheme is to use compressed air. Since I will be using boxed tubing, I could it for the reservoir. Then plumb accordingly with a small compressor on the truck or in the trailer.
Anyone wanting to weigh in on this question is appreciated.
