From your post. When you hookup, and pull 6 links. you are putting 1300lb on the rear. Something ain't right. the entire tongue weight should only be in the 750 range. no way the trailer should add 1300lbs
to the rear of the truck.


I agree...i wish i knew how to get more weight to the front of the truck and back to the trailer axles.

What do I do? My only solutions that I can think of is 1000 lb bars or getting a different hitch or a different truck.
Your scales data indicate a tongue weight of approximately 1200# and a trailer weight just under 6000#.
The resulting indicated tongue weight percentage of 20% is unusually high.

You need to determine why the indicated tongue weight is so high.
When you weighed the truck only, was it loaded the same as for the other two weighings?
Do you have a lot of heavy items in the front pass-through storage?
Have you added extra weight to the trailer's A-frame?

I suggest you make another trip to the scales.
You missed a critical weighing -- we also need to know the TV and TT axle loads with the WDH in place but with NO WD applied. That gives a baseline for the weight transfer calculations.
Be sure the load in the TV is always the same for all weighings. The driver, if outside the TV, always should be on the same scale pad.

True, i do think i need to reweigh and look at some options. I don't have any thing in the front storage that is overly heavy. I do have two six volts instead of the 12 volt. I don;t have the numbers of no WD applied unfortunately. I just was hoping that with the numbers i gave that were loaded up someboedy would tell me how to get more weight to front of TV.

Balance the trailer load for starters. Twenty plus percent is excessive. Don't worry about spinning your tires or number of links hanging until you get tongue weight down around 700-800 pounds and then your wd hitch will take care of it. Full water tanks forward of the trailer axles? Something is odd, like
Terry says.


Water tanks are right above the axles on the trailers. Numbers i gave when the trailer was loaded was with water and everything we need to go camping.

First of all thanks for all the responses.
I do need to re-weigh the trailer without the weight distributing hitch hooked up.

However, I was hoping that i had enough measurements to give you guys a idea of what i am going through.

Terryallan is right. 1300 lbs added to the rear axle is alot

I mean...
Truck with all passengers and full tank of gas…
Front Axle: 3542 lbs
Rear Axle: 2838 lbs
and then..

6 links free on bar chains
Truck with all passengers and full trailer with water and whatever else we need…
Front Axle: 3322 lbs (-220 lbs)
Rear Axle: 4114 lbs (+1276 lbs)
Trailer axles: 4928 lbs combined

and yes it wasn;t exactly the same. The ruck measurement is with nothing in bed of truck. The 6 links with trailer was with 100 - 150 lbs in box. So maybe tongue weight is more like 1100 lbs...still way too much.

I was just hoping to find a way to transfermore weight from the rear of the TV to the front of the TV. My only option is the hitch as we really can't move anything around in the box of the truck, and as far as the trailer goes same thing. We have the trailer loaded as best we can with heavy stuff at back and some lighter stuff at the front.

I've weighed the trailer with water and without and the rear just sags more.

I see lots of trucks with bigger trailers and the trucks seem to be level and the load equally distributed onto truck (both front and rear axles squatting). That is not happening with mine.

Thank you agin for all your help and responses. I truly appreciate all your help to figure out my dilemma. Like I said I am new to this and just looking for any and all help.

I think my option is bigger bars for wd hitch. We are getting close to max payload in truck as well with current set up.

Thanks

If i were to adjust the hitch height down one position (making the trailer nose down more) would this help distribution. I assume the tongue weight would go up though but with wd bars connected would that shove more weight front axles and trailer axles?

You should NOT see both front and rear axles squatting!
You should read your truck's Owners Manual for instructions on how to adjust the weight distribution hitch.
You should NOT attempt to make the front drop below the unhitched height.

You should re-weigh the truck -- including weights with trailer hitched and NO WD applied.
If the trailer's tongue weight really is 1200#, then you need much heavier bars.

Sorry Ron you are right. I do know that the front should never have more weight than unloaded weight. I guess what i meant was that the truck is just more level. I do need to reweigh the trailer and go from there.

With WD hitch hooked up...
Front Axle: 3322 lbs (-220 lbs)is this normal?
Rear Axle: 4114 lbs (+1276 lbs) i know this is not normal.

How or CAN i get the 220lbs lost from the front end back to the front end and at least get that weight taken off the rear axle? Is this even possible? Are bars my only answer?

Thanks again...i truly do appreciate it.

You need the WD to work more. That is the point of it, to distribute the weight from the rear axle (that 1300 pounds) back to the front axle and to the trailer axles too.

I am not familiar with your hitch. Does the head have an angle adjustment? Fewer links under tension and more hitch head angle are generally the way to increase WD force. However, with 750 pound bars and an estimated 1200 pounds of TW, you will not get enough WD to bring the front end down enough, exactly what you are experiencing.

Get bigger bars, re-adjust. Ignore the truck "stance" and rear height. Focus on leveling the trailer and gettign the front weight/height back to unhitched amount. The rear will be whatever it is, and it will tow well.
