Running a 4000 gallon poop tanker straight truck with bags is kinda sketchy. It rolls like no other going around turns. We ran dump valves to switches in the cab so when we spread on hillsides we can dump the upper side to help level it.
On big trucks, I prefer a solid setup over bags with something like that tanker. Bags roll in the turns a lot more than a leaf or block setup.
I know it's totally different than what your doing, but it's something to take into consideration

I had this exact setup on my Dodge for years. Had a 12v compressor with a tank in place of the spare tire. Tank had a pressure switch that controlled the compressor. On class 8 stuff that is always heavy on one side they will put a leveling valve on each side but it is rare because simple is always better.
The reason pickup guys don't like it is because they LOVE to tinker. They don't like the fact they can load whatever they want and never touch anything and the truck rides level. They like to push buttons and read gauges. If you want the ability to dump the bags most leveling valves have a dump option. Simply send air to one port from a switch and it will dump.
A lot of Kelderman kits use them, guess you should call and let them know it doesn't work.

I never said anything about mechanical load leveling valves being bad. I mentioned using them. I mentioned controlling the bags individually because a 4-link is going to be able to roll much more than the 2-link on a big truck, since the axle isn't doubling as a sway bar as it is on the big rig. So whether he uses mechanical valves, electronic system or just manually fills them, individually supplied bags is going to be the best course to take.
I've got the Accu-air E-level in my truck (because I like shiny things and have to tinker). I like that its fully adjustable and use it frequently. Being that you are only going with half a suspension, the benefit would be too little for the price tag. The mechanical valves is what I'd run in that instance. You can get them with internal dump valves if you're so inclined.
What bags are you looking at running?

I'm gonna buy the Accuair system as well. After looking into it, it looks so much more simple than what I was gonna do. Plus having the controller in cab, with the electronic leveling sounds nice.
As Far as bags go, I was looking at the Firestone 3500# rolling sleeve bag
I've heard other people using it, and the only problem I've read is that its huge. It's mostly the weight that it can hold that is why I'm looking at it. Idk if you have any suggestions for bags that can hold that kind of weight?

I used to drive trucks and we had a dump truck with full air ride, it used to be a truck with a 5th wheel that we converted to a dump truck... and yeah I totally understand what your saying, that thing would rock like a boat when it was loaded... also when you get going down the road it takes a min for the bags to level out and you get to rocking back and forth (like body roll back and forth) like your on a boat. I'm HOPING that my setup doesn't end up like that. but If it does, I will figure out how to fix it.

i havent seen a class 8 suspension that doesn't have top roll bars since the early 70s, there are no true two link setups on any truck that is on the road these days.
Don't buy into the fuel tank offsetting weight, we have one truck that only runs a single 150 and doesn't have any issues like mentioned.

Are you serous? Must be a HUGE tank because this truck is bagged, no sway bars and rides like a dream. Way more weight 10' in the air than a fuel tank on a pickup.

There are lots of Firestone bags that will support that weight. What you need to figure out is which ones, as they come in different lengths, which changes the spring rates in them. Also if you want internal bumpstops.

Couple resources for helping you find bags. The first link, on many of their bags, has a link to the Firestone data sheet.

I feel like we are starting to split hairs. Most people exclude the panhard bar when talking about the number of links. I guess in that respect, mine is a 5-link, as is every front end in Pre-2013 Dodges. Panhard or no panhard, the suspension in a big rig is still articulation limited which means body roll and weight distribution is much less of a factor when the bags are tied together side to side. That was the entirety of my point.

I have both on the same suspension, single valve with all bags tied together and dual with each side separated. There is no noticeable difference In how they handle.

5 gal tank will be plenty.. there's a 5gallon and a vise 450IG single compressor 12v.. compressor runs maybe 25% loaded.. full deflated to full Inflated loaded kicks the AC on runs a 90/125 on/of switch
Has 4 5900lb bags on it

Look for Firestone F2107 I think it was. It's a nicely sized rolling sleeve.

Listen people, we aren't talking about a mid or heavy duty truck.
If it's done right, it won't have any trouble. If it's done wrong, the body will roll because of small insignificant things.
I wouldn't mention the thing about the roll if I hadn't seen it happen. It's not any different than the conversation about why people don't like dumps to have bags. If the proper equipment is in place, it's fine. If not, the air system will have to compensate.

I want a roll of the 1/4" air line the pickup guys use that flow from bag to bag so fast it makes the truck roll on curves. Fire trucks could use it instead of that big junk they keep buying.

I had a few allroads (the exact car in that diagram) and they rode so nicely. No excessive body roll, the compressor did not kick on compulsively, and had a small-ish tank (approx 2g). The sway bars were not very big, and it was over 4000#. The key was in the programming, it needed to see out of tolerance ride height for more than xxxx time before it compensated that bag.

But remember what it was designed for, off and on road performance. Meant to articulate but not roll. Maintain height and composure.
But just goes to show a couple valves are not going to work with something.meant to articulate.
