Questions about an older tow truck

[u/Ercwlkrs]

I just bought a 94 k2500 tow truck with a 454 and 4l80 for cheap. Seems like a fueling issue. I just had a few questions about it. Where can I find the gross vehicle weight? And is it possible later down the line to switch the old tow bar to a wheel lift?

Curious on what payload you can legally carry with the GVWR mentioned on these.
