Perhaps that's because my background is aviation and safe flyers always use checklists. Several checklists may be appropriate, for instance one for hitching up, another for last-minute items before starting down the road, and others for routine procedures to be followed upon arrival at a campground. And we've always found it useful to refer to a checklist for loading up the RV, to make sure we brought the things needed. You might be surprised to learn that the very process of developing and verifying your checklists will put you well up on the learning curve toward becoming a better, safer and much less frustrated RV-er. And don't be timid about asking old hands about their checklists, suggestions and advice.
Campers are generally very helpful and anxious to offer suggestions.
So don't be too proud to ask for the knowledge and experience of others. You will probably want to pick and choose from the tips provided, tailoring the input from several sources to meet your own specific needs and preferences.
