I just got a Tornado about a month and a half ago. It took me about 3 to 4 hours to set it up the first time. Now, it's about 2 hours together and about an hour and 20 minutes to take it apart and get it on the trailer.
My T is also a Marstrom. They should be pretty solid. I didn't find any problems with mine. I would check for wear and tear on the standing and running rigging mainly.
Also, the TornadoCats Yahoo group has lots of good info. Mike Dobbs has plans for a tilt trailer.
Hope this helps,
