I have a 13,500 and a Honda 3000 with remote start bolted in truck bed with an lockable insulated metal cabinet with 10" axial fan pushing air out the other side of cabinet. I often open the cabinet lid but it depends on where we are.
I made the cord and twist lock long enough to point the rear of the truck away from the pin area where the cord goes into the front of the rig. Also added a plug and weather resistant cover on gen box where I can more easily plug in an extension cord or power my pancake air compressor.
