I went back to my college physics textbook and read about force, vectors and equilibrium. It explains the fulcrum both the way Kevin and I did. One using a ball suspended on a string when discussing angles of movement and torque then further clarifies torque useing a teeter totter when talking about equal non-colinear downward force.
Both Kevin and I are talking about the same thing using different analogies. My apologies Kevin!! I learned about fulcrums my sophmore year in high school. In Geometery class. Had more on them my junior year in Trig. Don't know why I took all them high powered math courses either. Spent the first 4 years after high school chasing cows....the last 30 have been holding a round thingy attached to trucks.

ok....take out a 2x12, 4 ft long. put supports under it 6 in. from each end, then place 300 lbs in the middle 2 ft of the board. the suports both equally distribute the weight 50/50. Now take the same "load", and move it toward the two feet at the end of the board, leaving the supports exactly where they are. now you will have the support under the "load" bearing more of the weight than the other.
now pretend you were going to slide the supports in each of the setups. If you move the same support (the one not bearing as much of the load) the same distance, you will end up with a DIFFERENT weight adjustment simply because the position of the load on the plank. so the 250lb per hole 'rule', is just a guide and should not be accepted as 'trucker law'.

you need to start somewhere with how many holes to shift an overweight trailer and 250lbs is as good a place as any. However, this depends on whether you have the same type of trailer or not.
Shift it and re-weigh!

You will find that the way the trailer is loaded also has an effect. If the load extends behind your tandems, the weight shift is not the same as when the load does not extent to the tandems. Use the "rule of thumb" to select the number of holes, then re-check your axle weights after you slide them. That's why it's only a dollar for a re-weigh.

Okay...here it goes. I picked up a load of Ice Mountain water in Stanwood, MI. Load was 45,252lbs. My first scale ticket showed the following:
11,840 34,200 32,660 I rescaled the load moving the tandems one hole forward....the new weights were: 12,000 33,960 32,740 The difference on the drives was 240 lbs. The difference on the tandems was 80lbs heavier. Now the load of water is probably evenly distributed from nose to tail (probably two singles in the nose but doubled the rest of the way back). thought of moving another hole, and reweighing, but then again, i'm a swift driver, and can't afford to waste another $1. ;-) I already have another load for tomorrow, 44k+. ill do the same just to see if there is a huge difference.

The funny thing is, on that load, and the load i'm about to pick up, my fuel routes have BOTH said "fuel up". Now i know better. When i fueled before getting the load of water, i only filled one tank, and i almost got to half tanks on the guage. Now when i pick up this Costco load, they want me to top off, but again, ill only put in half tanks. seeing how the water load only ran me 550 mi and this costco load is running me 400.
as far as the steers changing weights, i can think of two things. One, i was on the weight plate differently (dont know how). Or my other guess is this. If you take three tennis balls, lay them a foot apart, then put two pieces of wood, one going from ball a to ball B, and another from ball B to ball C.....then pump up ball B....the ends of the wood farther from the center ball will go DOWN. maybe this holds true when moving weight from the central set of wheels. then again, i'm probably wrong.

 As I remember from flight training 101, there is NO "standard" for weight and balance. Of course getting some women to be honest about their weight and the weight of their baggage can be a chore :angryblue:I have a really simple solution to this entire thread, weight it, adjust it and re-weigh it till it's correct. Or spend a bunch of money on one of them that mudd duck radios so you can run down the road with your echo up too hi telling everyone that your right and the rest of the free world is wrong. I guess after 21 years of driving I've been wrong this entire time abut how much weight is moved with each hole (I thought about 500#) on the tandems and each notch (I thought about 250#) on the 5th wheel. I think I'll stick to flying airplanes, it's a whole lot easier than the truck driving thingy.

What Pi$$ed me off is I showed the officer my scale ticket from sapp bros and told him I slid the tandems forward 5 holes to correct the axle weight , and he said those scale receipts don't matter ....? what kills me is that had I not weighed the load my axle weights would have been off but within in the 5% rule allowed for correction without fine .
Trailer sliders generally are 400# per hole except on the double holed trailers. 29+ years and never an overweight ticket. Check every load and double check it if you have to adjust it. Paying fines SUCK!
