Got the major portions of the truck blocked out: 
Looks a bit small but the truck doesn’t have a large truck bed so I suppose it’s accurate. I’m not sure if Blender 2.8 has background images like older versions of Blender have as I found it a bit annoying to move around physical images in my view port. I added an image as a background (Shift A > Image > Background Image) but it seemed identical to the reference image type so I’m not sure what the difference is.
On a side note this truck has me thinking this would make for a fun RC Combat game in AR. One of the big inspirations for this vehicle was the Twisted Metal series, it somewhat reminds me of Outlaw: https://www.youtube.com/watch?v=g92VTM5CXVM
