Help please

Thanks for all responses. First step is to find mechanic to come here. He has a reliable mechanic that owned a RV, so he is calling him tomorrow to see if he can look at it. No, of course we don't want to risk our lives and our motor home. I foolishly thought since it was inspected in September and we have hardly used it except for a few home games, how could it be something major. We're quickly learning that these things bleed you dry. A very expensive extra to have, that's for sure.
