Hi John! It is a pity you can't make the Star Camp. You would've been able to feel the weight of my GS12" Dobbie to see if it is managable for you.
I love the light gathering ability of the 12" but I desperately need better EP's as the one provided are pretty ordinary. They work, but can be easily improved upon.
If you need to move it around a lot (by car) I can give you the dimesions of all the GS Dobs if you need them. They are here on this site:

Good luck with the decision.
p.s. The Bintel dobs are GS dobs.
