| It's no different than the permanently mounted roof configurations. If you ensure your IDU is powered through one of the RV's NEMA5-15 type receptacles, the RV itself then represents common ground to the ODU. Once you bond the coaxial cable grounding block to the RV frame, that should be adequate to temporarily ground the tripod ODU. This should hold true even if you've plugged the RV umbilical into the RV park power grid.
More complicated - and probably not standard from RV park to RV park - would be if your IDU is powered through a receptacle outside the RV. You'd then have to search for the common ground relative to that receptacle. Don't be tempted to attach your ground wire to the electrical box, faceplate screw, or anything like that. You should never ground on the load side, always find the earth side.
