I've been working on terrain for a Sci-Fi Desert mining settlement. You can see the two buildings I've made so far here:

I wanted a civilian vehicle and a dumptruck seemed an obvious choice for a mine
Here's the vehicle it came from.
A Fisher Price dumptruck. It has train wheels for some reason, so I assume it came from a train set. It was 99 cents at a resale shop.
It makes sound and lights up when you press on the balast in the dump bucket. Unfortunately that had to go to make a place for models to stand, and I couldn't figure out how to easily wire up the lights with a switch.
I dug dents and gouges all overt, scratchbuilt a roof of .5mm plascard (a 99 cent for sale sign from the hardware store provides alot of material) and added a few
40k tank bits. The bump in front of the hatch is a mount for some of the pin-mounted machine guns that I've made for my other post
apoc vehicles.
The train wheels were removed and replaced with wheels from another 99 cent resale shop truck
I had to remove the balast and electronics, cut away alot of the inside of the dump and make a floor from plascard. The cutaways with the clippers I used came out rough, which really matches the inside of a dump which is usually dented, dirty and scratched. The roof is removable, though I haven't built an interior.
Painting was simple and quick.
-Prime with Black spraypaint
-drybrushes of color being sure to leave black at edges, interior corners and vents
-Thoughoughly drenched wash of Burnt siena (allowed to pool in crevases and left to dry overnight) to make the rust appear in places where rust naturally would
-Dabs of silver sharpie at the dents and gouges
-Sealed with a light dusting of matte spray.
I also painted the inside of the clear plastic head lights (The lowest pair of lights)once the bulbs were removed with silver paint before gluing them back in.
Here it is among the previously made mining buildings.
