My RV was smooth with no vibrations. My trailer is smooth. Are you on wagon wheels?
Things will fall off shelves when you turn corners for sure so bolt it down.
Lawn mowers have a lot of vibration, but wheeled vehicle should not. Sometimes you get a big bounce, but that is not a vibration and will not break a solder joint apart. I have never had issues with anything breaking in a moving vehicle. The issues people have is that they have things loose or not bolted down very good and it is not the vehicle vibration that is issue, but the item becoming airborne from a big bounce then the hitting back down of said item that creates the vibration and damage, not the vehicle motion.
Server batts are great for their flat'ish shape if you need that, otherwise I do not see advantage.
