I would like to be able to drive diesel pick-ups on forza horizon 3. I think adding in more mini trucks would also be a sweet thing to see also.
Vehicles including their respective engines:
Dodge Ram 1500,2500, and 3500
With a 5.9 or 6.7 Cummins
All generations of the trucks included.
Ford powerstrokes for f150, f250,f350
Any truck with a 6.6 Chevy duramax.
Rolling coal would be an amazing feature to the game and a lot more people including myself would be open to seeing them added to the game.
