Just expanding on Omnivorr's comments:
- 10" f/5 dob tube will typically fit across the backseat of most medium cars
- a 12" dob tube typically won't
So if you want portability for the occassional dark sky site visit (a treat not to be missed, especially in the mild/warm months), then I would recommend a 10" conventional dob.
If you go larger, I would suggest a truss-dob (eg. 12" f/5) ... but they cost more. I have compared my 10" Lightbridge truss-dob and a 12" GSO conventional dob side-by-side on DSO's at a star party and could not see any differences except for some very faint galaxy smudges which were a little easier to pick up in the 12".
Hope this helps.
