Tip: Tape a trailer height reminder near dash Mc D's, service area s in general. A lot of places restrict you, you need to know Mark, tape, highlight your brake activation plug s Some are not...
My "tip" and take on checklists...Depending on how much of a memory jogger you need, checklists are a work of art and change often.
Example...I can walk clock wise around RV and cover everything. EXCEPT my manual awning. I have a full page checklist for that darn thing. A big picture and steps labeled 1,2,3 etc.
My "maintenance" check list is my best checklist I have. Intensive, right down to "lube key ways on door locks".
