Sounds kind of excessive.
Your analysis is a little excessive but yes they often compare the picture when you return home.
Anything obvious like a bike in your possession upon return could arouse suspicion and likewise having an obvious item (say a jet ski) in the back of your truck on the way there but not on your return will likely be cause for a few extra questions to be asked.
Dont sweat the smaller sized items, they're not likely to be noticed but I would think a bicycle is usually pretty visible.
