I'll share my thinking Stan. When transporting my 9.25" I position the
mirror all the way to the back of the scope - to the end of its focus
travel in that direction - and transport the scope with the eyepiece end
facing straight down. This places the least amount of stress on the
heaviest part (the mirror) and its mounting mechanism.
Given the conditions you've related, I'd really be hesitant to lay the
scope on its side and subject it to lateral stresses. I place my scope
on the auto's seat on top of a couple of towels to help absorb shock and
place the seat belt around it. I also secure the upper portion of the
scope to the seat by tying it to the head rest. This has worked well
and I haven't experienced collimation issues. Your "mileage may vary"
regarding collimation - I drive a sedan with a softer suspension. I
suspect collimation will be in order for you when you reach your
destination.
