Dude, this is some awesome models. I love off-road machines. Great work! Here are some ideas I got and a few pictures: Your last picture of the exoframe kind of makes no sense. How will the doors open? Also, the hood is over-protected. There aren't many rock-slides when rock-crawling, the engine is in no danger of being hit from above. And sometimes you need to open it while off-roading. Here's a picture I found of a cool toyota rock-crawler. The doors are intact, hood too, so they tube-framed around them. They also chopped the frame and made the whole truck more nimble and short. I believe someone made a mod for a chopped off-road D-series, it might be worth it to make the two mods work together! This off-roader has another cool feature- tubed doors. These doors are cheaper to make (your model seems to have "aftermarket" doors, with bigger windows, they look good but I won't buy such pretty doors, they will most likely be bent and damaged! tubed ones may be a cheaper option, for more purpose-oriented off road builds. Also- Huge grill-mounted lights. also, I like how this truck has no front bumper, to increase the aproach angle. But that's not really the type of truck your'e going for. Anyway, hope it helped, or that the pics gave you some inspiration. Can't wait to try out the mod when it's ready!
