Anyone have experience with the WD and Ram 2500 air suspension?
It appears that the manufacturer fully intends for you to be able to use the Ram's air suspension for towing.
Page 525 (527/871) of the online 2015 Ram Owners Manual states:

Trailer Mode (Lowers the vehicle approximately 1 in) –

This position will lower the rear suspension
and provide load leveling for all loading conditions
including towing a trailer. After the “ALT TRAILER
HEIGHT” button has been pushed, it will blink continuously
until the trailer height has been achieved.

To use Ram's automatic air leveling in conjunction with a WDH, it might be necessary to use the "trial and error" approach of adjusting the WDH and then seeing what effect the air leveling has on front-end height or front-end load.
Then by varying the WDH adjustment, you should be able to compensate for any effect of the leveling.

Back to original subject/post

Here are pictures with the modified draw bar after WD adjustment. The picture of the rig together still looks like the trailer is too low in the front and the truck too low in the rear, but it is because of the angle of view and the less than exact reproduction of a slight wide angle lens. The second and third pictures show the truck is very close to perfectly level with a 100% front end height restoration, and the trailer is still about 1/2" low in the front. Believe I will live with this.

Just be aware that airbags can adversely affect the adjustment of the WDH.
If airbags are used to raise the rear end after the WDH is adjusted, the raising will decrease the amount of load transfer.

There are two ways in which airbags can be used in conjunction with a WDH to achieve both desired load transfer and desired rear-end height.

1) You could initially "over-adjust" the WDH (initially adjust to transfer more load than desired). Then add air to the bags which will raise the rear of the TV while tending to eliminate the excess load transfer.

2) After hitching, add air to eliminate some, but not all, of the rear-end drop. Then use the WDH to achieve the desired load transfer while raising the rear to the desired height.

Both approaches might require some trial and error adjusting to find the correct amount of "over-adjustment" or the correct amount of initial lifting via airbags.

Some users prefer the first approach because they find it easier to "fine tune" the adjustments using air pressure versus fine tuning by changing number of links or amount of ball mount tilt.

Thanks for this Ron....
would something like this be an option to airbags and a way to get my back end up a little?
