jnm30327, congratulations on your summer trip!
I think you may have missed the middle scale segment by pulling too far forward.
You’ll want to do a 3-pass method next time:
1) Truck and trailer connected with WD.
2) Truck and trailer connected without WD
3) Truck alone.
Watch to make sure the front axle is on one platform, rear axle on the next and the trailer on the last one.
Measure your front and rear fenders height from the ground to the fender opening on each pass to help understand if the WD is doing its job or if you need to make adjustments. This gives you an idea of how level the truck is.
The number to watch carefully is your rear axle scale number vs. the Tundra’s Rear Gross Axle Weight Rating (RGAWR). We had a RAM 1500
that’s rear max was 4100 lbs. We were right at that number before stepping up to a RAM 2500 with 6390 lbs. RGAWR. You’ll find it on the door sticker. No more payload worries!
Hope that helps!
