"We learn from our mistakes; the smart person learns from the mistakes of others." 
Ask, in advance, about anything you don't understand or need additional info on. There is a wealth of hard-won knowledge here and you will get more good answers and advice than you know what to do with!
You will find that your learning curve is steep at first but tapers off rapidly with experience, mistakes, and learning through others (forum). I have gotten so much from the various RV forums that educated and kept me out of trouble.
Welcome to the forum and happy RV'ing.
