Hover truck modeled in Blender 2.82. Works well in any real-time engines like UE4. Textures aren't the best, but head over to any free pbr texture website and find slightly rusty materials. All are included except a material in the truck bed. (all free just search free pbr materials). There are 3 boxes in the back that are all separate objects. The truck is also made up of may different objects, and none of them are attached yet so if you want to edit it easily, you can.
Pictures rendered using Eevee (bloom, screen space reflections, ambient occlusion, and an HDRI from hdrihaven.com (canary warf) were enabled/used) The holographic sides were made using a checker texture from blender mixed with an emission and a transparent shader
The lettering on the sides are the cause of the majority of polygons, so If you want real low poly, just delete them
