Yep it was RTS, any truck I downloaded got modified into RTS. I downloaded that first Bigfoot Realism Test that you put out there and I loved it, that's what sparked my interest in it. This truck, along with being and RTS truck had the center of gravity put right at the back of the engine (I believe) so I could swing the rear end around corners without it pushing too much. It handled really well, I was surprised at how much of a difference that made.
I'd wouldn't mind seeing what you came up with for the third version of them, I wouldn't drive a truck that wasn't modified so I loved this concept. I remember emailing trainboy911 back and forth because he had all these trucks he wanted modified and he didn't know how to do it, so I'd send him the ones he wanted and then send him some that I already had made; I had HOARDS of those things lol. I'm kinda surprised there wasn't too much interest in them, I know there were people still working on them but being that you were the first you probably had a better handle on it than anyone else.
