"THIS" is a biggie for those with the 3500 rear air when unhitching. If you are slow about unhitching the rear air system will start trying to re level and give you a big startle when un hitching. I read on another forum of a guy thinking it was all the fault of his new to him B&W hitch.
So here is the way to unhitch and hitch if you so choose.
When backed into the spot where you want to unhitch go into "Settings" then select "Suspension" then select "Tire Jack Mode". This will keep the rear from moving while unhooking and hooking. I touch no controls after unhooking then the system goes back to Alt Ride Mode as I had it set. I leave mine in Alt ALL the time.
Hope this helps with someones frustration!
I really don't see a need in all that. The way I do it is I get out of the truck and chock the trailer tires. I then lower the front landing gear enough to take enough weight off to let the truck come up a 1/4" or so. The truck will release the air out of the bags to let it drop back to the ride height it was at. I don't care how long it takes me to get to unhooking the height does not change. When I unhook the truck pulls right out with no change in the truck. Works perfect every time. No need to put in any maintanence modes. It won't matter whether it's a 1500,2500 or 3500. If it has auto level and you take the weight off the truck the suspension will adjust accordingly. Now if you lift the trailer to the point that you are lifting up on the truck too then you will have trouble because the system will dump all the air out to try and get the truck to ride height causing it to bind on the hitch or cause the truck to drop to the bump stops ( 1500 and 2500 only).
Well maybe you should come and show me how to do it. The truck will raise up higher than "ride height" when taking off the load then it wants to drop back down. Maybe yours is different as it's a 16?
I am not the only one that has has the hitch clunk when pulling away.
I lift my kingpin to the point it is slightly separated from my hitch plate.
Next time you do it lift the fifth wheel just enough to raise the truck a quarter to half an inch or so. Do this right after you chock the trailer wheels. Don't do anything else. After you have done this (with the truck running) then drop your tailgate, release your hitch and the power cord. By the time you get back into the truck it will have released the air out of the bags and you will have a small air gap between the king pin head and the hitch head. I would do a video if I knew I could get it posted.
Will be a while but I will give it a try.
Just lift enough weight off for the truck to sense the change in height. Give it a minute and you'll hear it dumping the air. When you pull out the truck will come straight out and not lift or drop.
