I recently watched Arthur lug his 16" Skywatcher dob components to the trailer up at Bretti (I was up on the hill at the time or I would have offered to help). Arthur's is a truss design, and even with his bad back he seemed to be able to move it around.

So what are the opinions: At what size do they get unmanageable?

I am assuming a open truss design, so that they can be broken down to move.

I'd like to find the biggest aperature (dob) that I can reasonable manage to move to astro camps - looking to upgrade from my 12" GSO solid tube to 16" or larger.

I'd love a 20" Telekit but I believe the cost of shipping and the optics would scare me off, but the 16" Lightbridge and GSO truss models are very close in price and seem to be more in my price range. Views on these?
