I have the book you're referring to. I really love Bob Livingston and his editorials in Motorhome mag but the book seems very general in nature. I bought it when I just started rv'ing about 20 years ago. Since then I've gained most of my experience and knowledge from doing simple rv maint tasks and asking questions online. I subscribe to tons of info online as well- much of it very enlightening. You'll never stop learning- that's for sure. One thing I have not done is take an actual rv repair course...as two of you have mentioned- it would be a great thing I think. Have fun in your rv learning!
