Well:
I personally own an (89 half interest), 92, 93,93,97 and the guts from an 03 that are for a crew (2) project all with cummins along with the remnants of a 93 and 92 that I am salvaging to keep the others running for cheap and to (cummins) power a Ramcharger. That is seven first gen trucks and two second gens
I doubt that makes me the winner. Just a bit more addicted than some.
