Probably not great to be posting in a years old thread but I found out who bought the truck and what happened to it.
Long story short a group bought it and custom re-built/painted the truck, this is either a good thing or a bad thing depending on your perspective.
This is Loader now

Might make a fun little article or wiki trivia tidbit. (Edit: just looked on TFwiki and this whole Speedvagen thing is actually listed in their trivia section on Loader's page so I guess this was already know by them but then again I don't know when that was updated since I've never seen that note until today, either way it has not been documented on a news site like here and TFwiki seems to be the only place that has make note it.)
