Truck capacity

[odyknuck]

Ok I want to match a Truck Camper to my 2013 F250 6.7 diesel with 8' bed. There is a sticker on the door that states tire specs and max payload of 2365#s.
Am I to assume that is the max load for the factory supplied tires or for what ever tires are on it? The GVW is 10K for the truck. The axles are front 5900 and rear 6100#. I also want to tow a 28' cargo trailer behind that could weigh up 9100#. Please advise.

That is correct, but you will have a hard time finding a truck camper that is only 2000 lbs when loaded.

So as I review the posts I have concluded that if I install the Air Bags I bought and bought a set of higher load tires for my stock wheels, then a truck camper in the range of 2000#s would work for me with the trailer towing. Note that it would be rare that the trailer would be at 9000#s. Most of the time it would be in the 6000# to 7500# range.

The brakes are different only on the DRW. The SRW's share the same brakes and axles whether they are F250 or F350.

Pay attention to the above suggestion. This here is the weak spot.
You probably have the same axle as the F350 dually but you have weaker rims and tires. I believe that is the primary difference between your truck and the super duty.
Going to the higher rated rims AND tires will give you the Capacity that you seek.

By the way, gotta' love that 6.7 diesel. Wow~what a performer!

Tires, rims, axles, and springs have all been discussed. Brakes are all the same I take it?

No. F250 (gas and diesel) are vacuum, F350 (diesel) is hydro boost and gets a bigger master cylinder. DRW's get bigger pistons in rear brakes.

Yea no dought they have the power. I thought all F250s are refered to the Super Duty now.

F350 is a Ford Sterling. DRW pickups are Dana 80"s

I had 7000 lb springs supporting 8000 lbs. As soon as I aired up the bags to where the overloads were not fully engaged, my truck would have much more bounce and sway when relying on the bags as the main suspension support.

With my new truck's 13,500 lb rear springs, I have not run it yet with my trailer. So far it is stable with no suspension aids hauling my 4000 lb TC (about 9000 lbs currently on the rear axle).

The air bags on our trucks were designed as supplements to the primary suspension and should not be confused with bags used in big rigs or even a Kelderman setup.

Your experience is very different than mine. On my truck, I had to remove the overload springs to install the air bags. The air bags did the job, empty truck or loaded with the TC. Unfortunately, I went against my past experience, and I let myself be persuaded to add a leaf. No problem with the TC loaded, but big mistake with an empty bed.

I will point out there are big rigs that are air bag suspension only, no springs.

Helper springs would help you, but a heavier spring pack is almost as much and a cleaner install that will allow you more options to remount your bags.

Very little weight is added to the front of the truck. You may want add heavier dampening shocks to the front and rear, but the front springs are fine.

[odyknuck]

So a set of helper springs will take care of the problem? Do I need to do any thing on the front axle?

[Bedlam]

You have to remember these air bags are supplemental suspension and not primary. This makes them good for leveling out sag but your spring pack needs to do most of the work. This is much more noticeable when carrying a truck camper since you are carrying a lot of weight much higher than you would if it was a fifth wheel or travel trailer.

[odyknuck]

Hmm! Is not an airbag a spring? I Offroad with a lot of guys who use only airbags and standard emulsion shocks on their Buggys. The air bags is what holds them up off the ground. I understand that the WDH is not the same as the sway bar for the truck. I only mention it for the trailer towing aspect.

[Bedlam]

The air bags will not do it for you. You need adfitional spring rate to carry that weight and not just leveling. The anti-sway bar I referenced is bolted to your axle and frame to reduce body roll of your truck - This is different than the hitch anti-sway for your trailer.
