Just from the specs, IMO, Rago for sure!
Rago: 1/8" Thick, STAINLESS STEEL, 3 mounting holes, 1/2" Hole - Powder-coat should take that down to a blond one over 3/8" - ready to roll!
Cali: Unknown thickness, Unknown Metal, 2 mounting holes, 3/8" Hole - If that hole was drilled out to 3/8" pre-powder-coat, you'll have to cleanup the hole to accept a 3/8" CB antenna and in doing so you just shot your powder-coat integrity.
The only thing I like about the Cali Raised over the Rago is how it matches the contour of the truck and how it is boxed in on 3 sides versus the Rago 2 sides - looks more neat IMO. Let us know what you go with and how you like it.
