Thank you all for your best wishes!
We finished our two night trip and things went pretty well. I have found a lot of little things wrong. However, two must be addressed.
1.) MAJOR: the black/gray discharge pipe is not well-aligned with the sewer (flexible) pipe, making removing and replacing the sewer pipe nearly impossible.
2.) Significant: The Owners' manual describe blow out system does not exist.
Both these lead me to believe the water panel has been worked on. I will be looking for a thread where I can discuss these in detail.
Oh, and I need more money
