We all learn by asking questions, never fear.
As for a departure checklist this is what we use. We have two laminated copies, one in the truck and one inside the trailer. We each divide up these tasks. I think its best to use it every time and in the same order. DW and myself cross-check each other prior to departure. The precheck items I do while she is still busy inside the trailer and ahead of the other items and while I pack up remaining stuff outside.
Since each rig and operator is different there will be many variations to this process, use what works best for you. Its all about safety and reducing risks and damage.
As for a days end list- don't have one. This really depends on location, weather, length of stay, etc.
Enjoy your adventures.
