I'm sure there is plenty more new "Do Not" that can be added. Such as 1. When truck goes in for service, don't put dirt or grease on my door handles, steering wheel, etc.
2. Do not have keys and other stuff in your hand that will scratch on the door near the handles when getting in.
3. Do not slam my doors either. My girls do stuff like that cause the door is heavy and they are 3 and 4 years old so they figure the door is heavy so they slam it.
4. Do not use your foot to keep the doors propped open so it does not smash your leg. This has not happen in my truck but I have seen I others do it to their own.
