My next door neighbour and I lifted my A.D. cab off, it was stripped to the bones i.e. no doors (basically a shell) We're both big guys.
It was a struggle,taking into account items such as the chassis, running board outriggers etc.
If you stumble you'll do yourself or your cab some serious damage.

Do as the others say,get some more bods or a hoist!
Good luck!
P.S I've just been diagnosed with a hernia!!! (Seriously!)

Go Figure!!!
