Even if it's 4wd it depends on which transfer case you have
LINK. Then if it has one that is flat towable it depends on what your rig will tow and the ACTUAL weight of the GC, not the book "curb weight" which is almost never the actual weight.
Your rig's tow capacity depends on its weight (actual again) when ready to travel subtracted from the GCVWR. or the hitch capacity whichever is less.
Good luck, I strongly suspect that, as heavy as the GC has gotten over the years you may be a bit over.
EDIT: Sorry, almost forgot
and enjoy that rig!!!
