I love making awesome vehicles from their base model. But there is only so much you can do. I do not know how to mod or anything like that, but I know there are a lot of content creators out there. Maybe add things like more styles of roll cages, more rims and tires, body parts. Yea, the Gavril D has fender flares but not like real baja style body panels. Things like off road style interior with electronic odometer to make it like a real off road monster. I while back I came across a mod like this but it was pretty sketchy and was not really good. So If anybody could make a mod like this, It would be amazing.
I might still have the OG Trophy Truck mod downloaded on my old PC (of course the mod is broken but someone might be able to resurrect it)
The DJLopper mega pack mod has a Roamed and D series that are pretty close to trophy or desert rally setups. They are the only way to fly on Ghost Desert's dunes. https://beamng.com/resources/djplopper-mega-pack-mod.451/
Yea, but it does not have that real "trophy truck" feel, you know. Maybe the people who did the monster truck could work on one, that is the best mod I have ever seen.
