Fresh water spigots or faucets in National Park & National Forest Campgrounds, have fresh water spigots with small diameter spouts with no thread for a hose. This is done because the faucets are meant to be shared by all campers. The Water Thief is made of rubber and fits over the spout. Some campers use a hose clamp to attach it securely.

“RV Electrical Systems: A Basic Guide to Troubleshooting, Repairing and Improvement” covers both AC and DC electrical systems and is another must have. Excellent 12 volt coverage and the best source on 120 volt AC systems. If it’s not covered in this book, you can probably get along without it. The authors go into extraordinary detail without getting into engineering “lingo” and they tell you things nobody else does, and those things many authors assume you already know — that you don’t. RV Electrical Systems is available at Amazon.
