Desperate for airbags or something to eliminate rear sag

The AVS replaces the coil springs rather than supplementing them?

 

So my understanding is that Adaptive Variable Suspension and Load Leveling Rear Height Control Air Suspension are two different things, but they are often packaged together.

I believe the Load Leveling Rear Height Control Air Suspension are, essentially, air bags that replace the coil springs.

The only system I'm familiar with where OEM air bags supplement coil springs/leaf springs for the rear axle are on the Ram 3500. But I think this option reduces the number of leafs in the leaf pack compared to the standard feature (no air suspension).

If the air suspension failed in the 3500, you could un-hitch your trailer and drive un-loaded. If your air suspension failed in a system which replaces the coil springs/leaf springs with an airbag, you run the risk of the vehicle being squatted to the ground and, perhaps, undrivable.

 

yes load leveling and AVS are not the same and not always together, in the lower trims they are never together.

they only way you would have an issue is if an air bag popped, but you can also have a coil or leaf break, same thing.

the auto level air system is great and I recommend it to anyone who hauls or tows often.

 

If you had a leak, and drained the entire system, or a pump failure etc. The truck would just sit on the bump stops, which are a chunk of rubber that act as a stiff spring. You would be able to drive to the dealer just fine.

The auto level air system has been amazing for me. I am not going to discuss how much weight I have put in the bed combined with large tongue weights, but the air system handles it VERY well.

 

You could... but I would wager that given X number of miles, the number of air suspension failures would be magnitudes greater than a traditional coil or leaf spring suspension on passenger vehicles.

If the air bags supplemented a coil spring/leaf spring setup, you wouldn't need to worry about the truck riding around on its bump stops. Also, it's a comical sight on the road when you see a vehicle with a failed air suspension.

 

your taking a pretty pessimistic view here, the sky could also fall.

I like the way it is now, it rides awesome in combo with AVS, tows awesome, hauls awesome, toyota makes stuff that lasts, Im not worried about it , if I buy another tundra in the future, it will have to have this system or I wont buy it, just like this time.

 

Plan for the worst. Hope for the best.

 

It's listed at 5724lb dry, with a GVWR of 7600lb. I haven't weighed it loaded. I do have a tongue weight scale, and loaded at it's max (full water tanks, etc.) it has 900lb of tongue weight. I'm quite careful how I load it and how much stuff I put in it, so figure the GVWR is pretty close to the heaviest I'll ever have it. I had a '19 Ram 1500 and a '18 Ram 2500 gas. I like the Tundra the best for towing this trailer. We go out about 6 times per year. Usually only one of those trips is over 3 hours 1 way. If I towed more, or longer distances I would get a diesel. I get a pretty consistent 10mpg (I live in the foothills of the Sierra Nevada Mountains, flat land would probably be a little better). That's about exactly what I got in the Ram trucks as well.

 

Airlift Air bags with compressor cured it for me.

You guys were saying? Looks like the rear of this truck is "hella sagging" - almost like the Carolina Squat.

 

kinda a piss poor example trying to prove a point

he has a 3” shitty lift is not oem and said “ I assume the tongue weight is”

if you don’t like it, don’t buy it , what’s the point of trying to say it’s shit to those of us who have it, especially with stupid examples
