How do you store/secure your portable generator?

Since I tow with an SUV and not a pick up, I have my eu3000i bolted and locked to one of these using some lock bars I made out of tool steel. I suppose given enough time and the proper tools it could be stolen but it would take some planning and more than a little time to get at it. I just pop the cover off, plug in the TT and let her run.
