Tommy,
You found your way here and that is great. There is also another forum that is all ways older than this. The only reason I mention that is that the people at the other forum have seen just about everything, but they are old (like me) and don't have your energy to pursue everything any more. They can, like here, be an amazing source of information. I see you started with a great sigfile. That makes things way easier for those that might like to assist you.
You have just been dropped into a community of amazingly supportive and helpful people. To make the best use of this, you don't need to do much but ask questions and pay attention to the answers.
The other thing you need to do is contact the local chapters to get to a rally to see what others have done. Before you spend any money, you should realize that the interior of these coaches were all very carefully designed. This makes improving the layout more difficult than it might seem. There are still things that can be done, and most all of them have been. You just have to find the person that did it and ask how well it worked out.
As above, Welcome aboard.
Matt
