How do I attach the toolboxes
 

I am putting a set of toolboxes in my new trailer and would like to know how to attach them to the wall. There will be a lower cabinet and upper chest (total height will be about 5 feet) and I plan on screwing the chest to the cabinet. I was wondering if I can just attach the tool boxes to the trailer wall by running screws throught the back of the tools boxes and into the trailer wall studs. Any ideas would be appreciated.

you can do it any way that suits you , but the floor in a trailer is a lot stronger than the walls..I took the casters off and bolted mine through the floor , no problems in years,,,Paul :D

this is the way I would and have done it also. And bolt the top to the bottm.
