forgetting something can cost someone elses life, at your expense. Sure you learn something, but is it worth it? To me, no. I agree with repairs. Some things i do on my own, but i laughed at for going to the dealer. People don't understand that i not only loose money doing it myself, but i get behind in work, customers get mad, and thats money i'll never get back. I would rather drop the truck off at the shop, hop in another one and continue working. I might break even at the end of the day, but everyone's happy, and thats one less headache on my part.
