Welcome to the club bigdan120. Feel free to ask questions, this is a nice friendly group of people here with lots of knowledge they are willing to share. No doubt you have read that we like to see pictures too.
If you have the VIN number handy, Sunline Fan (Jon) maintains a registry of VIN numbers and may be able to give you some info if you send him a PM with the number. He is EXTREMELY knowledgeable in the history of Sunline units.
Good luck and happy camping with your "new" T-2051.
