Here are a couple of comments from Planet Robby:
"Robby is running his new truck. Kellon Walch will be the co-driver.
Sometime after Baja ( just like every year) is when they will probably begin to send out pictures."
(Guessing about what exactly RG will be driving:)
"TOG said it is a truck. So that rules out any kind of buggy sort of car. Mike K keeps reminding it's a WRC course this year. So I lean towards a front or mid engined smaller truck."
