I am also in the beginning of my hunting phase and looked into the TX coach. My first question would be about service records/history. From what I gather to not take a Newell back to mother, or have a quality bus mechanic take care of the PM and maintenance issues can be asking for bigger problems. there was a suggestion on drawing fluids and having them sent to a lab and checked - a brilliant idea too.
There is a lot going on in these coaches and I would want a bottom up inspection by a knowledgeable third party before making a deal.
