If you went to a 3:73 you would see a bit of improvement, but unless you intend to keep the TV till it rots I doubt it will be justified in fuel savings.

The main reason for most rear axle changes is to improve the towing capacity. This is always in the other direction where the cost can be justified by the improvement.

If you have and use cruise control you will see your best fuel mileage. We all have lead feet. On my diesel Jetta that can be 4 mph, 36 to +40

This is not my opinion it is my experience. If you want to see what a heavily sprung TV can do to you trailer here are a few pictures of the body separation across the front of my trailer. Keep in mind that I live in New Jersey, known for the poor roads and camp in Pa known for worst roads, and that I had towed this trailer over 150,000 miles when this repair was needed.

Every rivet from the door to the opposite side inside and outside have sheared off or pulled through the skin.

The pieces are from the outer body shim and typical of what I found.

The majority of the time the trailer was towed using a 2500 Suburban with the one ton spring pack.

That same majority has never driven a well set up combination, either. One can be faulted for paucity of experience. Or, that there is a difference between informed opinions and all others. I use a 3/4T for a number of reasons past towing just this trailer. And am heavily loaded when I do tow it. An 1100-lb TW pretty well mandates it. But with a 700-lb TW and good WD there are other better choices than trucks.

And a DRW is not more stable. It would be closer to such if the Steer Axle were the same width as the Drive. It can feel more stable on dry roads but never on wet. That, alone, should keep one away from them. I've driven them to make a living and have good experience with them in all weather with every kind of load and trailer. I wouldn't hesitate to have one with a big GN or 5er. But it's slow going under some conditions.

I have had two new 1/2 tons(F150's)and two new 1 ton(F350's) in the last four years.I have pulled my 28ft Airstream with both.
My background:
I have been in the automobile business for close to 40 years.I have ordered thousands of new vehicles.I also won the Chevrolet product knowledge challenge three years in a row.I am a member of the Chevrolet truck hall of fame and a diamond member of the Chevrolet Legion of leaders.I am also certified in ordering Medium and heavy duty trucks.I might also mention I am a ASE certified technician.
The above references to damage must have come from some older versions because this is not true with the newer 3/4 or one ton.

You are also incorrect on a 1/2 ton riding smoother with its springs at or near maximum capacity.Sorry but I call BS.
People on this forum come here and ask legitimate questions only to get fly by the seat of there pants people's answers.

Technology changes rapidly and things have really changed when it comes to light duty and medium duty tow vehicles.

Yes, things have changed. Ram 1500 and 2500 now have coil springs in the rear, and full air suspension is available in either. Not to mention a diesel engine available in either.

My 07 ram 2500 ex cab short box, 6speed auto which is double overdrive, 373 ratio 1525 rpm cruises at 64mph up and down hills, it does have a solid ride, just slow down when the road gets rough, common sense cross country trips the fuel average is always at 12 mpg actual.When loaded the steer is 4260 rear is 4580 and the trailer is 7520 so all is well...

I am just curious, with all your Chevrolet knowledge why do you chose Fords as your tow vehicles?

Our current tv is a '12 Ram 3500 SRW 4x4 (only difference between it and the 2500 is the rear spring pack & no TPMS). I'm really not in favor of anything that hinders its performance in snow (like fat tires or DRW). Just my $0.02 though.

I prefer Ford technology over Chevrolet today.

Hi Moflash

If you ride in the Airstream on the same road at the same speed you will notice a substantial difference in the road shock transmitted to the Airstream. In a vehicle with Independent Rear Suspension the ride is very smooth with very little vibration. A half ton with a live axle transmits some road shock but it is still not terrible. A 3/4 ton is dramatically more harsh to the point of being painful to sit on the sofa over the bumps.

Though the suspension in the 3/4 is firmer I think the unsprung weight of the heavy axle is the biggest contributor.

I hope this helps.

Maybe in the past this would be true but not today with the increased spring packs used 1/2 tons and larger axels and differentials that the mfg's have chosen to install.Towing with close to max payload limit provides virtually no spring absorption when a bump or pothole is hit this the bang that is felt on these occasions.Of course independent suspension will provide a smoother ride but they are hindered in towing capability by smaller axels and additional universal joints.And there tendency to squat when pulling a load on takeoff.Independent suspension is far from ideal in design for real world towing.Sorry now we are off topic

I made the above reference to damage and I did qualify my comments to take into consideration the quality of the roads I frequent. I did not mention that the truck was a 1997. And yes the newer trucks are not designed as much for truck usage but rather status symbols. Thus generally providing a softer ride. The fact still remains that you can dissemble an Airstream over time with the right conditions of suspension, hitch, and road conditions. I offered that as evidence worth consideration. As with every thing else to be considered when choosing a TV.

I will stand by these comments. However I do not recall mentioning that a "1/2 ton riding smoother with its springs at or near maximum capacity". My comment was " An empty 1/2 ton truck is designed for a soccer Mom and thus has a soft ride. An empty 3/4 will not have the soft ride you are referring to". Near maximum is a completely different situation. That is a function of the many different rear axle spring packs offered for a given truck.

We find our 3/4T to be more than adequate for our 25' ...however, there are some concerns about harsh ride for the AS.

We have owned a 1 ton dually to pull a fiver, and it was obviously too much truck for our AS. MPG=12.5 ( on a "good" day)

Our 2012 2500 Ram has the same towing capacity ( ! ) as the dually, rides much better, MPG= 14+ while towing, comfortable, short bed > shorter turning radius...easy to park, etc. MPG on the road not towing = 22+!

3/4 ton more than adequate for AS'ers.
