The best purchase I have made is a book titled "Idiot's Guide to RVing" Third Edition. You can buy it on Amazon for less than $10. This book gives instructions for every type of travel trailer, fifth wheel, truck camper and class A, B, C. The book has checklists you could print out and use like a pilot in a cockpit. It lists everything you will need including lists for bathroom, sleeping,cooking,clothing,outside gear, etc. It also has a step by step checklist for hitching and unhitching and also for hooking up at the campground and unhooking. The book covers everything you need to know about your propane, plumbing, electrical and troubleshooting. I don't leave home without this book.
