Joes Auto RV and Trucks

My RV broke down, (the front pump seal o-ring needed to be replaced) and I had it towed to Joe's RV shop.  The only reason that I am giving him 2 stars is because he stuck to his word of charging me for 6 hours labor and came to pick us up from our hotel after we had to turn in our rental because our RV was supposed to be done.  My father was with me and has a mechanic business of his own and was unable to fix the issue due to no tools and no lift.  The job was a 6 hour job max.

So we went and turned in the rental car and went up to the RV shop at 330 and once again they said it wouldnt be done until the next day, hopefully by 1.  I was so upset that I was in tears.  About 1 the next day, they called and said it was done.  They did come pick us up from our hotel and took us to pick it up.  We got about 10 minutes down the road and the check engine light had come on.  I called them back and they told me that it couldn't have anything to do with them because they only w
