No problem. We are actually on vacation too, currently in Napa Valley.
There would be no problem with FAGWR, RAGWR, or GCWR. I just may be over the truck GVWR if it matches your weights. This is where I am at with the truck unhitched and unloaded, full fuel, no passengers:
Estimate with 318SAB
FAGW=4120, FAGWR=4500 (380 lb margin)
RAGW=5450, RAGWR=6084 (634 lb. margin)
GVW= 9570, GVWR=9200 (potentially 370 lb. over)
GCW(est)=9570+8140(318SAB axle wt. loaded)=17710, GCWR=22000 (4290 lb. margin)
Look good to you?
Thanks again Jim!!!
