I just gave a hard look at the skids available and only found two that attempt to distribute impact away from transfer case. Asfir and budbuilt. Others either ignore (stop at crossmember) or make it no better, like the arb.It is a bit curious. The skid looks to be more bombproof than the TC case itself. And likely stronger than the structural components the TC is mounted to. From a systems design perspective, I'd rather the skid be the sacrificial component, deforming and taking some energy out of a hit. Or like your suggesting, mounted to transfer energy to the main structural components rather than to the TC.
