There are lots of files available for 3D printing as well. I have scaled up some of the Bergman kits on Thingiverse and Wargaming 3D has one as well. Some nice crew figures are also around. While I have printed mine in 3D plastic, a friend did me some in resin and the quality is much better. I have also printed some stowage as well to use for the heavy loads that these truch carried. One of my stowage pieces is actually from a Finnish sled load and I made some mods to fit in the back. Another 3D guy was good enough to provide me with a file for British "flimsies" and they are part of the load. In the early days of the LRDG, they had no options for fuel until the Jerrycan became more readily available.
