I crew off and on with a PNW based class 7s ranger, so I'm used to a rule book limited race vehicle. The rule book allows allot of changes to a Sammy that should close up the side kick advantage. Desert racing is all about prep, set up,race strategy's and not over driving the truck. I think that a purpose built Sammy to the current limits of the rules would be competitive against the sidekick trucks. Has there been a Sammy raced in the series yet? To quote Robert Duvall in days of thunder theres nothin stock about a stock car!
