Fueling when heavy, will it add weight to the drives?

I have used the tactic of getting a trailer up to a few miles per hour then hitting the brakes. Sometimes it even works.

In fact, that is the one single thing that trailer brake levers are good for, IMHO.

BUT not all trucks have independent trailer brake controls. Mine does not.

I have also used railroad tracks and speed bumps to help break loose trailer tandems.

Sometimes though, nothing works except using chocks or a curb.

I suppose you could use chains and a big ### chunk of concrete or another truck's tow hook, but that would almost certainly be too much trouble.

Doing tandem movements on significant inclines can be helpful too. If one exists.

The BIGGEST problem with simply using inertia for shifting stuck tandems is that the harder you have to work the tandems with an inertia method, the higher your chances are that you are going to shift the load inside the trailer.

Your mileage may vary on that. Scatter a load of early season strawberries, and someone will be very unhappy with you.

I just howl my wife's name when tandems need sliding and wont give it with me shaking that tractor down.

ZZZZTH there it is. Thank you wife.

It's a woman's touch don't you know.

Not to be a nitpicker, but it weighs 6.92 lbs a gallon.

Different blends at various times of the year weigh slightly different. I usually just round it to 7 pounds per gallon.

I calculate 8 lbs per gallon, to be safe, no matter what time of year.

I had to read it three times before I noticed he mentioned tandems.

I did. This is what he said.

"My current load with tandems all the way forward scaled at the following weights.

Fuel- 5/8

Steers- 11480
Drives- exactly 34,000

My 5th wheel is fixed but I was always under the impression that anything forward of the 5th wheel doesnt add weight to the drives but to the steers similar to how center of gravity works in a plane. My question is should I just fill up to 5/8s or just simply fill up?"
Notice there's no mention about his tandems

Question...I see a lot of talk about non-moveable fifth wheels. Why would anybody in their right mind not have a fifth wheel that's adjustable.?
What's the advantage to a fixed fifth wheel?

So that new hire idiots does not adjust 5th wheel too far forward and then tear front of reefer engine off the trailer.

If in winter add 2000 pounds of snow on top of your trailer. Find a low walnut tree and scrape trailer clear.
