I went through this same thing regarding trying to find an aftermarket air system for my 2010 EB. I'm curious to see how the airbagit and airlyft systems work. In my case I'm pulling a 30ft travel trailer and using an Equalizer brand wdh. As mentioned, a little bit of sag is ok according to the Equalizer support team as long as the front axle is planted correctly. I've moved my hitch height, added/removed washers on the system to try to get a more level line but what really helped was raising the wdh bar height settings on the trailer. The more aggressive setting has almost removed all sag.

This weekend I swapped out my old strut/shocks to a set of Monroes and the truck is sitting almost 2 inches higher and feels much more stable, less body roll. I'm betting those old struts were contributing also to the sag and hoping when I hook up the trailer again that I see even more improvement.

If you have over 50,000 miles on your struts/springs you might want to look into replacing those and see if it helps.

I forgot to mention, I did try the Sumo Helper Springs in my desperation and the pic I posted was with the helper springs installed. All the do is make your ride bouncier and I don't like them. Yes my camper is long, it is a 27 foot camper.

I have the same complaint. My trailer is 23ft (6500lb GVW) it has about 700# tongue. My Equalizer WDH is set so I have no front rise, but the rear sags quite a bit. Inflating my rear tires to 45psi (51max) helped with "feel". I still can't find a proper air assist rear spring package. Damn IRS coilovers. They sound great until you want to buy anything to augment them.

Have you tried moving up the bar settings on the trailer side? I did and it helped quite a bit. Front end didn't move much but rear sag was reduced quite a bit.

Unfortunately I don't have very good picture illustrating what you're looking for. When I installed the WDH, I didn't have a scale, so I measured the gap from the ground to the bottom of the front and rear fenders with the intent of minimizing the changes. Here are the only photos I have. I arrived late at night after driving from Texas to California. The stabilizers were down, but they didn't lift the trailer, just kept it from rocking. The vehicle is a 2017 EL Limited.

I saw your post above and will be trying that very thing in the spring.

Are you setting the ball at the right height?

That video assumes the truck doesn't sag under the weight. When my camper is on the ball, the truck sags. I've adjusted the ball so that when everything is in place (weight on ball, bars in place) the trailer is level.

This sounds like more weight needs to be shifted to the front on your WDH setup. Guidelines provide for 10 - 13% of the trailer load to be on the rear hitch. I may be useful to take your trailer to a commercial scale to get the weight, then use a tongue scale to get everything distributed correctly. Here are some simple instructions below to get the tongue weight. It uses the combined weight - vehicle weight to get the tongue weight.

  • Drive only your vehicle onto the scale with the loaded trailer attached; make sure all four of your tires are on the scale.
  • Take the weight measurement, and this is measurement X.
  • Detach the trailer from your vehicle while your vehicle remains on the scale.
  • Take the measurement, and this is measurement Y.
  • Now subtract Y from X, this is your approximate tongue weight.
