In the early days when many of us were just starting our RV lifestyle, keeping our RVs repaired usually required a trip to the RV tech or mechanic knowing it was going to take a chunk out of our wallets.
Our alternate options at the time were to seek help from a friend (often more harm than help), or go to the library and pour over repair manuals--if you could find one that you needed for a particular job.
But that all changed with the internet age, especially with search engines like Google and Bing, and altruistic RVers who post clear and concise step-by-step directions, photos, even videos of everything from testing and analyzing your RV systems and appliances to completing the necessary repairs or replacements--including the tools and parts you will need to do it.
If you haven't tried it yet, the next time you have something fail, Google it. Look at several different web pages and find the one that makes the most sense to you. You will be surprised how much maintenance and repair you will be able to take care of yourself with proper instructions--as well as all the money you can save on shop repairs.
