Thanks Kev,
Looks as if the Rocker Box is the thing to hold me back. I will concentrate on setting up a trailer for transport. I'll consider ways to minimise vibration and the like. I also agree that collimation is not that a bigger deal as can be delt with on setup.
A trailer will be an improvement on my current method of shoving in my 12" dob into a small sedan. Just a little more cost involved but somthing I can use for dump runs ect... Just have to learn to Back the damn thing up

Will be good to have space for passengers in my car when I go out too. No probs lifting heavy weights...story of my life
What do you use for a shroud? Any probs with obstruction?
