Locating a dealer

Hello Everyone,
This is my first post, so I apologize if I ask something stupid, or don't know what I'm doing.
We have looked at one TM 2720sl at the new dealer in Grain Valley, Mo, Show Me Campers & Boats. It was on a very, very cold Saturday morning we made the drive from Lawrence, Ks, where we live.
Are there any other dealers in the Missouri, Kansas, Nebraska, Colorado within a reasonable weekend drive to look at TM's ? Since this is a brand new dealership we thought maybe a dealer that had been in business for some time might be better to deal with on a new trailer.
There is a RV show in Kansas City, Mo. Bartle Hall (I believe) that we want to attend but I don't know if any other dealers will be there.
Thanks ahead for any ideas.
PJ
