As you no doubt figured out, it's a 350HP CAT C7, with an Allison 3000MH and 4.88 gears.
I also did some research with Winnebago engineering and determined that upgrading the tires to 285/75 LRJ upped the capacity of the chassis to the same as the 40's (same axles). With everything aboard, including 40 gallons of water in the trailer, we gross right at 38,600# (29000 + 9600). The heaviest vehicle we haul is the toad, at 4520#, other two are 4200 and 3880, respectively.
The trailer is a custom built Pace Shadow GT, with an extended tongue, 12K axles, and other goodies. It serves as a worker barracks when we work races - so the volunteers don't have to pay for lodging.
