GMC AFKW 352 weight?

[Ridgecrest Rob]

Anybody know off the top of their heads (or has a manual) how much one of those beasts weights? I found a COE GMC workvan...want to get my ducks in a row before knocking on the guys door. It's been in the same place for many years, moving it may be a bigger challenge than actually buying it!

Thanks in advance
