Sherry,
Based on what you have written, I am assuming you purchased your coach from Best Pre-Owned RV in Houston. I purchased a 2003 Holiday Rambler Endeavor from them, before we acquired our Beaver. I am familiar with their operation, as we stayed on their property for several days while we went through the Endeavor and made a list of things that needed attention. We also purchased an Easy Cary Extended Warranty from them. They include a 12 month one with the purchase, but Marilyn allowed us to purchase an additional 3 years coverage at their cost. It was very useful when an air compressor belt froze and overheated several components. Easy Care paid for the repairs, less the deductible.
In fairness, BPORV repaired every single item on our list. In addition, since we had to leave before the new windshield arrived, they had it shipped to our service center at home, and paid for the installation. That said, when we were looking for our Beaver, we contacted them and they told us Beaver coaches were beyond their expertise so they tried to avoid them.
Going from the Endeavor to a Beaver triggered an immense learning curve, which has not peaked in the 5+ years we have owned the coach. Patience, ask questions, talk to people who own a Monterey like yours, and it will be sorted in time. This forum is priceless. There are lots of experts here. I'm not one of them, but I have a working understanding of the Hydro Hot, Power System, Aladdin, and the components. Please reach out to me or others here. There are no bad questions.
