Truck Sag - Desired Amount?

[OR_Brewer]

So I was doing some reading that said a little sag in the back is actually desirable. I went out and measured with my rig hooked up. Here's what I've got going on:

Unloaded (no TT): Front = 38", Rear = 38.5"

Loaded (TT) with WDH: Front = 38.25", Rear = 37.5"

Is that good? Or should I go up a link on my WDH chain (currently have 2 loose).

If that's good, and since I DO have airbags (deflated for this test), would it benefit me to inflate so that the truck is level? I know it doesn't redistribute any weight but maybe the level ride helps with stability?

Thanks!

I think if the ride is good and headlights are still aimed fairly well an inch won't matter too much... at least that's what I tell my wife.
Plus the Carolina Squat is "in" right now.

Many W/D hitch installation guides suggest that a difference of .25"-.5" on the vehicles front fender well height between hitched and unhitched is the target number. Check your particular hitches install guide to see what they recommend but I think your in the neighborhood.

Then test drive it loaded as you would take it camping. To me, if it doesn't drive right, being at the recommended measurement doesn't make me happy. It needs to be both. If you get the measurement right but not happy with the ride, look at where you can move weight to to change your Tongue Weight.

Maybe full water tanks, Maybe half full, Maybe more of the heavier stuff inside the camper towards the front, maybe more towards the middle. And yes, since you have airbags, test them with different settings to dial in the ride to what you like the best. That's their main benefit.

Good Luck in tuning it in just the way you like it.

Unless your tow vehicle is a 10 wheel tractor, I think those are great numbers. I would not use the airbags to level the load. When I was running bags on my Tundra, I would load up the bed with whatever gear I was taking and use the bags to level the truck with no trailer. Then I would hook up the trailer and set up the WDH to get about your numbers. I wouldn't add air to the bags to level the truck at that point. I played around with PSI in the bags a lot while towing and I could really crank up the rear of the truck when towing. The issue with that is you seriously unload the WDH and that is not good. Just like when you hook up your trailer and use the tongue jack to unload the bars so they are easier to get hooked up. I could do that with my air bags. So don't do that.

All truck sag once loaded that's what the springs do . normal the wdh puts some weight back up front so you're not nose high . from your numbers you look good
