Congratulations Perry. I am also involved in motorsports and use mine as a "mobile headquarters" at race venues. Before that we flew to all the races and stayed in motels. It's so much better staying at the venue, sleeping in your own bed, and cooking out. We often cook for a couple dozen people. They get to where they rely on you to be there and feed them.
Be sure to check out the Newmar Owners Forum. More than likely somebody has a rig like yours and can point you in the right direction for almost anything.
