If you will look at this picture
http://www.kellrobotics.org/images/s...e/DSC_0026.JPG
you will see a rolling wire cart. It has front doors that fold down the sides when in use. The red tool box on the right is 2.5 feet wide. On the left side we have about 2.5 feet of open space that has a trash can.
We have added a retractable bar that extends 2.5 feet to the left that is the coat hanger bar.
This cart is 5 feet wide and 24 inches deep, and about 60 inches high. Make sure that you can transport it in your trailer. Most economy trailers do not have a door height large enough to accomodate it.
At the bottom of this page is our cart :

A lower cost version with out front doors is here on the bottom right:

We will maintain this setup in our shop and then just roll it to the site. Everyone knows where everything is.
Roll it in. Roll it out.
And you can secure it.
