He had aftermarket bull bar and side /brush bars but skip hit the driver door / sill but yes - the steel bars are the key as radiators are remounted in the steel bars…. Very solid mounting…Exactly. I'm seeing this as a long term wear issue not a brute strength issue. I seriously doubt the ROW bars and better brackets will prevent damage to the radiator in any serious collision whether with an obstacle or a a sack of soft tissue. All that may be needed is some amount of reinforcement even if it's less than "robust"and needs to occasionally be replaced. Perhaps some kind of flexible or vibration dampening fixture could serve when traveling long distances over broken ground and not rouse the ire of the authorities.
Sidenote: Ronny Dahl didn't lose the auxiliary cooler when he met Skippy on the road. The right wing/bumper/door took a pretty good hit as I remember. Was the lack of damage to the cooler due to the steel bumper or the supports?
