Can You make this Oshkosh L-ATV into low poly?

I need to replace the Humvee model in my game as it looks old.

Just do the exteriors and forget the interior, the accessories, the transmission and the tires I have better ones and they are already low poly.

File is huge so I compressed it in 7Z

I’ve been modelling for a few years, so I think I’d be able to do it. PM if you still need help.
