I can't find another truck like mine , is it a rare breed ??

1998 GMC Sierra Quad Cab K3500 6.5 Diesel Non-Dually longbed. Can't find any out there. Google says they are out there but I can't find any for sale.

I've seen them before but they are few and far between. The 7.4's were a more popular option back then and pretty much all the ones I see are owned by siding crews or a construction guy.

I have a similar one. It's a 2000 K3500 quad cab long bed single rear wheel "SRW". It is a 7.4 though. It's a "Camper Special" which all had gas engines. So that's different.

It's used as a farm truck, so the body is a little rough (that dent near the fuel cap is from before I bought it, 2012 I think). Here is a pic from 2016.
