+1. Also did a week long tour across PA with no lock at all.

Some yocal kid in WY did try to steal my stove after I left it out in the open close to a road with only a post rail fence separating the tent camping area from the road. Fortunately, I was sitting outside the laundry room, saw what he was about to do and made a bee line for my site. He saw me and took off.

Other than that, critters have been the most common perps.
