Huge thanks to @iRetr0x for his support with modeling, please give him support as he has several engine mods himself.
Make sure you are running the most up-to-date version of the mod, as some of the older ones don't play well with newer BeamNG updates.

Custom Configurations:
D-Series:
Duramax Pre-Runner:
Custom built for all your baja needs, this one is a short cab configuration, so just meant for strictly business.
Duramax Extended Cab Pre-Runner:
Custom built for all your baja needs, includes an extended cab for tons of room for equipment or people.
Grandpa Special:
Old man purchased, old man owned. One owner truck complete with ALL the chrome, completely stock, extremely low mileage.
Sport Truck:
Extensively modified, makes so much power, the rear tires basically cannot do anything. A handful to deal with but a ton of fun. Fancy paint job included!
Work Truck:
Straight from the auction block, this old water service truck was purchased new from the Department of Water and Power. It served for 16 years before it was auctioned off, and had a hidden bonus, a Duramax engine.
Junk Truck:
Saved from a nearby field, most of the body is rotting away, but this hides a 600HP engine and several suspension, braking, and steering upgrades.
Roamer:
CopHD Duramax:
Another one saved from the scrap yard, simply because it is cool. A build from a well-known truck customization shop, this cop car is fitted with a frame, suspension and engine from a D35. The engine is hopped up a bit for police use as well.
RoadSport Duramax:
Simply a RoadSport package optioned with the diesel engine. Nothing super fancy besides being one of the rarest Roamer combos on the planet. Only available in red.
Adventure Duramax:
When the facelift for the Roamer came out in 2002, some were unsure at first then this came out from a Beam Mod shop. This Roamer is heavily modified to be a beast off-road. Even being swapped with a 6-Speed Manual transmission.
The models were removed in 0.1.5 due to texture issues, but don't worry they will come back.
