Pretty cool idea for a thread now let's see if I can remember...likely not going to be in the correct order.
Trucks Driven:
Avenger (RORMJ)
Grave Digger (KOTH, first ever driver to be TQ, win racing & freestyle)
Mopar Magic (KOTH, I think I won either racing or freestyle one of the 2 nights at Wildwood but I don't remember for sure)
An Escalade (KOTH)
Black Stallion (KOTH, freestyle win)
General Tire (KOTH, one of the very first KOTH events)
Blue Thunder (KOTH)
Iron Outlaw (KOTH)
Monster Mutt (KOTH, tied freestyle win)
El Toro Loco (KOTH, tied freestyle win)
Backdraft (KOTH, KOTH mini series champion)
Titan (ROR Outlaws season 1)
The Punisher (Custom Season, overall freestyle champion)
Maximum Destruction (Season 1, & 2, freestyle champion of season 1, season 2 personal record of 7 freestyle wins)
Problematic (AME2, ROR Outlaws season 2)
Keystone Krusher (Mayhem in Christmas Village)
That's the ones I can remember driving in actual events with highly competitive racers, and now for a little history of Keystone Krusher, Problematic and The Punisher.
Keystone Krusher
There was one other version, white with brown checkers on the rear similar to the Keystone Beer/Mistress trucks and brings us to the current ROR version.
Problematic
Has always been a Dodge until ROR where it became a Ford but that may change eventually.
The Punisher has seen many many different variations so here are a few to keep from hogging the thread.
