Updated the Backpacker today. Some design changes. More efficient layout (more containers, no large conveyors anymore). Wheels are now placed correctly when building the truck via projection. Some decorative DLC blocks used (conveyor caps, exhaust pipes).
Have fun.

say multiple grids, loading the biggest grid, missing wheels, wondering what else is missing

UPDATE:
- replaced the 4 cargo containers above the wheel suspensions with a hollow armor construction, so the suspensions have space to move.
- reconfigured the suspension settings
- large reactor is now connected to a conveyor system
- underneath the exhaust-pipes I placed a small reactor (left) and a small cargo container (right)
- use the small reactor to power up your truck if you completely run out of energy
- use the small cargo container to add uranium to your reactor (as long as your truck has power)
- removed some blocks that where blocking the wheels in some steering angles

Thanks for the feedback. I will try to fix this.

The back wheels lock up on the cargo containers and they seem to be to close together. It gave me some trouble when I used this build. Also the reactor could not be refilled due to it not being conveyor connected to anything. Just want to give you a heads up. Freaking amazing build though. Love your stuff.

YAY!
