You are not getting the correct weight readings.
1.You need to weigh the tow vehicle and trailer WITH the spring bars on
2. Weigh the tow vehicle and trailer WITHOUT the spring bars.
3. Now weigh the tow vehicle only.
My tongue weight was listed as 785 and using only the weights from 1 & 2 I got 760 ponds. Nope, I was wrong, using all 3 weights I was shown that my actual tongue weight was 1020 pounds!!! Your tongue weight reading is likely wrong. Please read my post and the first 3-4 replies explains how to determine your actual tongue weight with these 3 weight readings you need to have done.
Went to the scales, how do my numbers look?
