Can't adjust Reese hitch

I bought a 2014 Sinature from Camping World and had them install a Reese dual cam system. It drove beautifully with no sway whatsoever. When I got home from Albequerque to MN I found that they did not make any adjustment for height and that they left out the shims so I started over. I ordered shims from Reese and then started to redo the setup. MyTV is a RAM 1500 Limited 2014 with air bags on four corners. I leveled the AS and backed the RAM up to the trailer and shut off the air system. The hitch ball was 4" higher than the receiver. I noticed the hitch ball was straight up and down so I tilted it all the way down. That got me two inches lower. My question is: what can I do to make up for the two inches. I can't see any way to adjust the hitchball lower than it is now. Any solutions?

Whoa, can you please post a picture? I have the dual cam setup myself and a Ram 1500 with a 27ft Signature, but tilting the ball is not the correct method.

I don't want to give up incorrect advice, so it would be helpful to see a photo of your hitch. I had to make some adjustments to mine, and dialed everything in back in June on the road.

You're truck will sit a little lower with the weight of the trailer on the receiver, but probably not two inches. You may need a hitch stinger with more drop.

It is good to tilt the hitch down in back. Here's a good method for setting it up.

Height adjustment of Reese Dual Cam Weight Distribution Hitch

I suspect you may need to purchase a WD Shank

From this site;

Reese - WD Shanks

My set up, while a bit taller works well with one of the shanks, you will have to figure out the correct size.

As to tilting the ball head, this depends on how much weight distribution you desire. More tilt shifts more weight onto the TV. I think the idea is to have the TV balanced on all four wheels as far as weight.

Tilting towards the trailer shifts the weight to the trailer, tilting towards the TV shifts the weight towards the tow vehicle. But it's not how you'd get the hitch lower.

I needed to replace mine with a proper drop shank to get the height right. Which you can see my drop hitch in the picture above. Mine is also a Reese drop and was ordered from eTrailer. The model I have is none reversible, so it only works as a drop. The one that came with my system could also be used to rise.

Need clarification

As one tilts the head towards the trailer does this not add tension to the bars, pushing them up more at the trailer end? And, as the bars are pushed up, would this not force more weight onto the TV?

I had my ball tilted toward the trailer, was getting a couple hundred pounds more on the front TV wheels, so straightened the ball head up (tilted forward) and this lessened the front bias on the TV and now I am about equal on all four TV wheels.

Thanks for the input. Please read Dougs response in this thread. It is a great article.

The factory also told me that I needed a hitch bar with bigger drop. Thanks

If you had the work done by a "certain" Airstream RV Company in ABQ.....I'd check, double check, EVERYTHING they touched.

The instructions do say how to adjust the tilt, I finally took the time to do mine according to the directions, before our 4000 mile trip east this fall, and it made a big difference..I also raised the ball height up to almost 20" so it would be level...

It is a good rule to never have a Dealer set up a WD hitch. They do not have the knowledge of how to do it nor will they spend the time to do it right. I have spent hours to get a WD system set up correctly because ever change in the ball height, head angle, number of chain links hanging, and level of the trailer requires a start from scratch approach. This is a cause and effect setup and anyone who makes a single statement, number of links hanging, on any part of the set up is blowing smoke at best

Andy's article is a start but I have to discount step #6. The angle of the ball is the principle adjustment used for transfer of weight. As the angle is changed it transfer weight proportionally to that angle to or from the TV/trailer not to either or the TV and the trailer for a given set of bars. As the angle is tilted rearward additional weight will be placed on the front axle of the TV and on the trailer axles. The ratio of this transfer is a function of the wheel base dimension of the TV and the distance from the ball to the center of the trailer axles. NO single statement can be made regarding this as no 2 rigs are the same.

Actually, the ratio of the transfer is a function of a) the TV's wheelbase, and b) the distance from the TV's rear axle to the midpoint between the TT's axles.

Yes, a single statement can be made:

The ratio of load added to the TV's front axle divided by load added to TT's axles is approximately equal to b/a, and
the ratio of load removed from the TV's rear axle divided by load added to TT's axles is approximately equal to (a+b)/a.

For example, if TV wheelbase = a = 140", and TV rear axle to TT axles = b = 280", and 200# is transferred to TT's axles:
TV front axle load increase = 200*280/140 = 400#, and
TV rear axle load decrease = 200*(140+280)/140 = 600#.

The load transferred to the TT's axles is a function of:
1) combined downward force exerted on A-frame by WDH lift chains,
2) longitudinal distance from ball to lift chain brackets, and
3) distance from ball to midpoint between TT axles.

Specifically, load transferred to TT axles is approximately equal to combined lift chain force times ball to bracket distance divided by ball to TT axles distance.
