Just traded my '17 Platinum Ecoboost for a '25 Platinum Plus (703a). Had bags on my '17 to prevent squatting when I pull a ~6,500 lb travel trailer. I haven't hitched it up to my '25 yet but expect it will need bags too. Do these new high trim levels come with factory bags or self leveling features? I don't see any bags, but do see some sort of linkage on the the rear suspension that seems to measure sag. Anyone know what this is and what it does/

 

I think that system is to help adjust the lights so they aren't lighting up the tops of trees when you are hauling a lot of fat chicks. LOL

 

That's the on-board trailer load weight scale. Check your window sticker for details.

 

This got me curious as I have heard both responses.
So I looked through my long PDF owner's manual. Here's what I found: Onboard Scales (If Equipped) Onboard scales uses sensors mounted to the suspension to calculate the vehicle's payload.

I didn't see anything about the head light sensor, not that it doesn't exist.

I was particularly interested in this as I am adding the RAS HD and BILSTEIN B8 5100 rear shocks and want to keep the rear close to the stock height, this being one of the reasons.

 

Removing the factory lift blocks kept my rear at the exact same height when I installed the RAS HD.
