There is a new setup video available that will show you everything folks have been trying to describe in answer to your questions. It is very good. A picture is really worth 1000 words especially if it is a moving picture!
Go to
WWW.trailmanor.com
along the top menu bar select show room
scroll down to "Video Media Center"
THere are 4 videos there one of which is called setup which will answer most of your questions.
Merry Christmas to all!
Thanks Trail Manor for the cool videos!
