james j neiweem Posted May 14, 2020 Share Posted May 14, 2020 First gear makes many models of by gone fleets using R models as subjects. I may be wrong but I think many of these fleets never had R models such as PIE Preston Campbells transcon etc. I may be wrong. I am especially curious about Transcon and the R model. I know they had Wilson U models. I read on facebook that Transcon had R models with Cummins 903's. Speaking of the 903's why weren't they ever turbo charged.

Maxidyne Posted May 14, 2020 Share Posted May 14, 2020 IIRC Wilson had U models with Cummins 903s because they went around all the manufacturers taking bids for the truck and engine separately. Mack was the low bidder on the truck and Cummins must have a lot of 903s laying around because they underbid everyone else with the 903.
