I spent today mounting the first of 2 security cameras at the storage units and doing this: http://www.phorce1.com/garage/ to the 2 10x20 units I have there now (also have a 10x10 for "stuff"). Can't take out the vertical poles and the "floor strip" may turn out to be "interesting" to try to pull up but this will allow me to move the trip hazards and tools out of my way so I'll have a clean path all the way around the bus that I'm working on. I will be moving the '74 from the storage unit near my house to this second bay soon. Now all I need is for whoever is in #67 or #70 to move out so I can have 3 10x20 units together. I only pay for one of them. And I'm not paying for that for the next 3 or 4 months because that is my "pay" for installing the cameras. If I get another 10x20 I will be paying $160 for 3-10x20 units and 1-10x10 unit. Less than I was looking at paying to rent a single-car garage somewhere. Gerald
