Congratulations on your maiden voyage! Sounds like you made the same mistakes we've all made the first few times out. But it sounds like you learned from those mistakes; which means you'll probably also learn from the advice others have given you. Many have suggested on other posts that new campers keep a note pad in the trailer to write down (while your camping) the things that will make your next trip better. Just remember, death is the only excuse to stop learning. And when you start taking your maintenance, packing, towing, backing, set-up, teardown, and safety practices for granted, is when you'll start making mistakes - some of which can be costly, harmful, or even fatal! Please read and follow the recommendations in your owners' manual. Develop a written list of procedures to follow for each camping-associated task. Don't get distracted from the task at hand. Once you start a task, finish it before you move on to the next. There is a time for adult beverages . . . and it's
not before or during the time you're on the road.
Finally, once the set-up tasks have been completed, sit down in your favorite lawn chair, put your feet up, and relax with the family for a couple of hours. Knowing that you've been diligent in your preparation, towing, and set-up makes this time all the more sweet!
Happy camping!
