I'm going to be moving soon and driving a moving rental truck with a cargo door that opens by rolling upward. These trucks have holes for a padlock on the latch.
My drive is going to take several days and all of my belongings will be stored in this truck in a couple of hotel parking lots. I've got a couple of Master locks but have heard that their security terrible so I'd like to invest in something to better protect my stuff. I figure that ~$50 is a small price to pay as insurance.
I found a youtube video with a seemingly proficient lockpicker describing some locks which have stumped him. He mentioned Mul-T-Lock and a couple others that he was unable to pick. And, from reading here, it sounds like Abloy, Bilock, and American Lock are also very secure locks.
I found some links on Google for the American Lock 5200 for $15-20 each. While Mul-T-Lock padlocks go for about $50 and Abloy and Bilock padlocks go for $70-100.
Are these American Lock 5200 locks that I'm finding for so cheap the right ones? Would I be better off getting a Mul-T-Lock or Abloy?
Also, I don't have any dimensions of the locking mechanism for the truck but if anyone happens to be familiar with the style of lock these rental companies use (it's a big latch at the bottom of the door) I'd love a recommendation of a size that would work. Here's a picture of the back of the truck that I found.

Thanks a bunch!
