How is the box and generator attached to the trailer in the pic with generator on front? Is one side open? Concerns about theft?
Here's another view. The box is bolted to the tongue frame. The generator and gas can are strapped to the box bottom, and the generator is locked to the tongue frame using a cable and padlocks. However, since cables can be cut with a bolt cutter, this method is not foolproof.
The box also has a locking top to prevent casual inspection of the contents, and when open, the front can be slide out for running the generator in-place.
