Precision shooting off a vehicle

[Namekagon]

Has anyone ever noticed any precision (or accuracy) issues when shooting prone off of a stationary vehicle? Such as prone out of the bed of a pick-up, or off a decent sized trailer? Does movement of the vehicle on the suspension come into play, or is there just too much weight for it to move in time to effect trajectory? I've used a platform on a trailer to get above weeds before, and everything seemed solid enough. I got a first round hit at 950 so I guess I can't say it caused any problems. But I've never tried to shoot groups off it for load development either.

Anyone ever see any issues?

Depending on how far out you’re shooting (or how high you have your magnification at), even a mild breeze would cause your vehicle to twitch and be noticeable through your scope.
