Thanks Tom for your post. I do the same basically. I check the tires by hand, but will add a thumper as well, I do look for obvious leaks and disconnects on the toad, run the toad as required by manufacturer, and any open compartments. I then depart for the intended stop purpose (read nature break for me and the dog )
I can't recall if I ever shared here before, but when we had our old rig we stopped so the DW could look, (HA), around a shopping outlet mall in Texas. I elected to catch a nap in the RV. Before I could settle into sleep, the dog began barking and I saw a head pass by the dinette window heading to the back of the rig. I had parked as the mallsecurity weenie wanted, by the outside edge of the back of the parking area. I initally thought the guy was going to take a leak on my tires so I popped out to chase him off. I heard a whistle as I stepped out the door and looked in that direction to see a doo rag wearin fellow look right at me then the back of my rig. Not thinking I went to the back to see what was going on, was halfway there when the first guy stepped out from behind my toad in a casual walk and never looked back. When I looked for Mr Doo Rag, he was gone too. I looked at the toad doors and it was still locked and check and all the compartment doors were locked and not tampered with that I could tell so I returned to calm down the barking dog. An hour later the wife returned and we left. I stopped at Sam's club a few blocks away to top off. While there I did a walk around and noticed that the brake emergency clip was on the ground as was the electrical conncetor for the lights, the driver side pin was partly removed and the safety cable D ring was opened on the driver side only... Those two were about to steal the toad.
It never dawned on me that I should have checked for the toad but with the key needing to be in to tow, we all forget to remove it when we stop for lunch or whatever. The other thing that sticks with me is that I should have not left the RV without calling the security or police. I also should have grabbed my defensive tool as well, I do since then.
