Mine goes in the tailgate corner of my truck bed. It is secured to the bed wall using the lockable steel rope. My truck also has a lockable folding hard plastic bed cover and of course the tail gate locks.
Makes for a nice OUT-OF-SIGHT secure spot for us when in travel mode or lock up mode. I just pull it out onto the tail gate when connected to the trailer shore power cable when allowed to run my generator at the camp sites.
My game plan was to keep the generator out-of-sight as much as possible and I have not had any thief problems using it over the past few years. It goes where I go. I would never leave my generator unattended at a camp site.

To me just sitting one on the ground next to the trailer, attaching to a front or rear bumper tray or chaining to a tree is just just saying "TAKE ME-TAKE ME" Thiefs will look for the easy target and can cut thru almost anything using a dremal tool or HD wire cutters.
Seriously - how long would these last...
