Hi Vespine
You will find the specs of GSO Dobs here:

FWIW: My 12" GSO Dob usually travels, fully assembled, in my Mitsubish van. I have transported it in the same manner as Wombat I.S., that is, in my wife's Mazda 4wd wagon with the OTA laid between the 60/40 split rear seats, and the rocker box in the back.
I move it around the house, again fully assembled, with the aid of a $20 trolley. No lifting or grunting, no probs.
Hope this helps your decision
to buy a 12" dob, that is..................
