Kolya.
I purchased a 10" dob from Andrews only two months ago. You're correct that there are no instructions but, as already said, there is only the chipboard base to assemble and it's pretty straight forward - it must be if I managed to assemble it! Just take your time in putting it together 9you should have plenty of that with all the cloud currently knocking about Brisbane).
I must admit the 10" is a bit of a beast size-wise. I keep mine in my living room and carry it upstairs to use it. This involves carrying the base, then the scope itself, before re-assembling. It only takes five minutes though. It's not too heavy, more awkward than anything else, but much heavier and it would be a pain.
I haven't transported my scope anywhere yet. I'm a little apprehensive about doing so but once this weather clears up I'm going to head to Maidenwell and hopefully get away from this light pollution. I'm also thinking of building a case to put the scope in, in the car so it doesn't roll about etc.
Good luck and I may bump into you at one of the seeing nights if I ever get to one!
