I personally don't care for running boards — especially the tube type. But GM lists some molded boards for the Dooley (Part# 12498019). A search here in DP reveals nothing about them. Anyone running them on a crew cab Dooley? Do you have any pics? That GM part# says for cab only (not box).

I think the ones you are looking at are the ones I took off my dually. They only go to the rear of the cab. They were a dealer installed option on my truck. They look similar to the ones the tahoes and suburbans came with stock. Ive never found any to go on the bed.

Have 'em on my Yukon XL that's for sale right now in the marketplace. They are stock.
