,

I'm not understanding the Original Post- were you belted in the passenger seat or somewhere in the back of the RV?

If the latter:

You probably wouldn't fear riding in the cab of a pickup just because you got tossed around riding in the pickup's bed- you just wouldn't ride back in the bed anymore....right?

Try thinking of this the same way- just don't get out of the seatbelt unless the rig's not moving, at least for now.

Good luck!
