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

Pulling Cabbage at 30 mph with 80K is much easier on a driveline than trying to slide tandems.
I used to tow years ago. Much of our business was due to folks trying to slide tandems and fifth wheels. And there is no need for it.

I'll back right on out of here now.

 

OK, I am going to try this one more time. I know and FULLY understand your point. I honestly do. I also have seen (or rather heard) universal joints busting. I had one to go out on me the VERY day I got my tractor. I get it. You are not, however, getting my point. The wear on a drivetrain from sliding a tandem and/or 5th wheel is considered NORMAL wear. A driver is not going to burn a clutch or over torque a drivetrain unless they just sit still with the engine at full RPMs and the vehicle not moving. If a driver is doing that they are not smart enough to even be in that dang thing. You keep making it sound like it is an either or situation, do it your way or call a repairman. Sorry I can NEVER agree with that. That is where I will dispute you.

 

You guys are worst than a bunch of ham radio operators, making simple things as complicated as it can get.

Now I'm not super trucker but I give advice and one thing I do advise is when you are at your limit with weight, just figure on filling the tanks to a specific level to get you to the next fuel stop, and fill them again at that level, this keeps you under while it takes extra time, you avoid being pulled in for being overweight.

 

In theory if you set your 5th wheel to where you’re a little over 12 on the steer and right at 34 on the drives you should never have to move it. After I took the lift axle off my truck I had my 5th wheel centered between my tandems for my first load. Scaled it and ended up moving ahead one notch. Now I’m 12200 and I haven’t touched it in 3 months. I’m thinking of going to a stationary just because it’s a cleaner look and I could have a smooth deckplate all the way back.

 

I see your point and I appreciate all the fixed fifth wheel info everybody passed along.
I wish we could just "set it and forget it" but it doesn't work that way.
We haul a lot of different trailers and different types of trailers with different load requirements and pin settings so a slider is pretty much a necessity for us.
LOL...one of our customers is a major utility company with a lot of job trailers, generator trailers, flats, and water tankers. We move the trailers for them. I think they sent somebody out and told them to buy all the trailers they could find but not to have any of them exactly the same as any of the others.

 

It comes down to if you need it or not I suppose. At my old company the Canada legal trucks had sliders but the rest were fixed. The only reason we had sliders going to Canada is because we had to pick up our lift axle and slide the 5th wheel back at the border to get our weight legal, and do the opposite coming back into the states.

The OP here needs to ask about having his 5th wheel moved ahead one hole at least, unless it creates clearance issues with the trailer. It needs to be where he’s 12k or a little over when he’s 34k on the drives. Maxing out the drives while being light on the steer means technically he can’t even gross 80k in most situations.

 

I like loads that wiegh 7 or 8 k it saves fuel agrivation and fooling around. ............ but as far as the first question is concerned you should be able to figure out on your own that if you are at 34 k you cant add any wieght so you can only replace the fuel your burning

 

Lighter, and really once it's set, you don't need to move it anyways.

 

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