1994 Mazda B3000 with hauling options package (heavy duty springs / rear suspension) = rated for 1800 lbs in the bed. AKA, MORE than a Dodge/chevy 1500.
Yes, yes, it does make you feel all warm inside.
But yeah, the most I've ever had in my bed was 2,100lbs of cow **** when I was working landscaping and picking up fertilizer. I make it home just fine but I really don't reccomend it, I came really, really close to losing a tire with that load.
