I replaced all the steel spring suspension parts front and rear in my 2012 Dodge 2500 HD Cummins with a Kelderman level ride air suspension. There is an expansion air tank on each side of the rear axle to cushion the ride along with an onboard air compressor and three gallon air storage tank. I have an external air hose connector by the rear license plate and a 25' air hose will reach the trailer tires as well as the truck tires.

The stiff steel spring ride is gone. Another trick for ride comfort is reducing the rear tire pressure to 45psi (per the manual) when not towing or carrying lots of stuff in the bed. It is still a truck and not a Cadillac, but the ride is much better than stock.

While the Firestone rear air bags are rated for 10,000 pounds, the lowest rated part of the rear suspension is the 6,010 pound rated axle. The Michelin 17" LT265/70R17E tires are rated 6,010 pounds at 70 psi out of 80 psi max pressure.

With all the modifications I have installed including a Hensley hitch (1.175 pound tongue weight loaded for camping) and two generators, gasoline, grill, two propane tanks etc etc in the bed of the truck, I can transfer enough weight to the front axle to be within 100 pounds of the no trailer weight and still have nearly a 1,000 pound allowance for the rear axle.

That means we could take a couple of folks along riding in the rear seat of the crew cab.

Since we have a 27FB Classic on order, I expect the tongue weight to decrease several hundred pounds as the extra items we added to the 25FB International are standard on the Classic. Fully loaded with the Classic in tow, I expect to be under the 20,000 pound combination weight by more than a thousand pounds.

Thus the half ton pickup class would not have been enough truck capacity for us.

Part of the reason your Expedition "squats under the load" may be the Andersen WD hitch you are using. The Andersen while a great anti-sway devise, seems to have failed in the weight distribution department when used with heavy trailers.

Point well taken....there is a BIG difference between an "air suspension" and add-on air bags.
I wasn't aware Firestone offered the complete system.
I researched their add-on and felt it wasn't worth it for our rig. Easier to Cat Scale and use the WD to level and aid in loading.

FWIW...our 25' Classic, loaded for Camping.
Tongue weight,


Bob

Update on tow Vehicle, 1992 Oldsmobile Custom Cruiser. I just upgraded the differential from 3.23:1 to 3.73 Limited Slip (Posi). It has a 5.7 L V8, Bilstein shocks, Moog cargo springs with Airlift 1000 bags and onboard compressor.

I have not towed with the 3.73 yet but will after I put a few hundred miles on it with this ring and pinion.\Dick

The truck you built sounds fantastic! It must be fun to tinker with.

I checked the Airstream specifications and it said the 27 Classic has a 9,000 lb GVWR. Unless I'm missing something, the pickup you've outfitted could tow a lot more than 9,000 lbs. Do you really think your pickup, fuel, and pickup cargo gross out at 11,000 lbs?

If your combined vehicle weight rating is 20,000, please don't load your trailer to 13,000 unless it's factory rated for that. The trailer, the pickup and the combined weight each have separate weight ratings and exceeding any of those individually is a safety problem (and a legal one if something goes sour).

I ran a trucking company and have a good understanding of gross weights.

Just sayin'

The Dodge is rated 20,000 for a combination weight. The maximum trailer weight in the literature was based upon the factory empty weight, which was not the reality when I took it across the CAT scales immediately after leaving the dealership. I considered the 10,000 pound limit of the largest Airstream as the heaviest trailer I would consider. We opted for a lighter model in the 27FB at 9,000 pounds GVW.

Since we will transfer our "stuff" from the 25FB to the 27FB, we will be in the 8,000 pound area even with the extra water on board (54 vs 39 gallons).

The truck axles (5,500 front and 6,010 rear) and tires can support a load over 11,500 pounds. We can plan on a 10,000 weight with no issues for the truck. Our current rig on the last trip with everything including the kitchen sink, so to speak, we were at 16,000 across the CAT scales. I can shift some of the stuff from the bed of the truck back into the trailer to keep the truck GVW closer to the listed 9,600 pounds limit.

We are still in the learning curve loading the gear between truck and trailer.

It's really going to pull nice on the hills with those new gears Colonel.

Will be interesting to see how high the RPM is at highway speed. Our V6 G35 has 3:31 gears with a 5 speed. At 100kph (60MPH) we are running 2,700rpm in 4th gear. Let us know how it works once you get the trailer connected.

Nice. The older trailers are so much lighter than the newer models, it's insane. My 34' International weighs less than a new 25 footer, just over 6200lbs empty.

For that kind of trailer, the Diesel Touareg makes a beautiful TV.
