When I bought my first class A RV, the old guy that sold it to me said " now all you need is a big tool box". There are books on how to do the repairs yourself, more fulfilling and then on the road you know what's happening. In some 45 years of RVing, my rigs have never been in the shop, all fixed myself, you can do it too.
