I wouldn't worry about it.
I travel with all the gear in my signature below, typically around 2500 miles per year. At a couple of star parties that I attend, there are a few miles of washboard road that shake my vehicle pretty violently. Often times, the astro gear is traveling in a cargo trailer, which has a suspension that doesn't dampen nearly as well as my truck or motorhome that is towing it.
The important thing is to make sure that it's reasonably packed. Most of my gear rides in Pelican or Storm cases with pluck foam to ensure a secure fit. The mounts ride in storage tubs, wrapped by packing blankets. And the telescopes ride either on the bed in the motorhome or camper, or seat belted in the back seat of my truck. That is, except the mirror box for the 14" dob. That either rides on the floor of the cargo trailer, or the floor of the motorhome.
The collimation on the 14" dob would never survive one of these trips, but that's no big deal because I collimate it each time I set it up anyway. The collimation on the SCTs rarely needs more than a minor touchup, and usually not even that. And I've never had a refractor lose collimation in transit.
