Then get to a cat scale and find out for sure what your dealing with... After I did my driveway wheel well mesuring and adjusting I went to a cat scale and got my weights...
Here I got weighed my truck alone.. ( I have 2700 lbs axles per my door tag.. and GVW of 4900 lbs)
front 2560 ( 140 left before over axles)
rear 1860 ( 840 lb payload remaining)
This is without wd hooked up..
2360 front.. ( Wow 200 lbs off front wheels..
2480 rear.. ( You dont get your TW this way by subtracting the empty truck weight FYI but 620 lbs.. Sheesh)
And to let you know my TW is advertised at 420 on the trailer sticker....
Trailer was dry here
3980
Now you see with my wd activated...
front axle restored to empty truck weight.
2560 Front (same as empty truck)
2200 rear ( 340 lbs on rear)
4060 trailer.. ( 80 lbs added to trailer from TW)
This is as good as it gets with my set up.. I drive 65 mph, have tires inflated to max when towing. Drives straight and true and never sway..
But its a lot of weight for the 190 hp s 10 v6 to pull.. But the s10 makes all its torgue at 2800 rpms and has 3:73 rear. Thats why I get away with it...
