One thing my wife and I started doing about 30 years ago was make it all a two person job. We both walk around the rig inside and out checking doors,windows, bin doors, locks ect. I walk the outside while she does inside then we switch. We both do the hookup and unhooking coming and going changing jobs each time. After a while my wife was very comfortable with it and started pulling our trailers and drives our motorhome. She has had to get us home a couple times and helped friends as she now knows how it all works. Sure saves problems. Odds I would catch it all are not getting better with age.. So for us its a team job.
Oh ya.. I am 75
