I am towing a 32 ft Cardinal and the rear sags a little and I have been told that my head lights LQQK high. The trailer tows real well and and I have no complaints...

Will Air Bags Help or Hurt? Also do you have any recommendations? (I ain't rich so be nice) LoL

Thanks Lee

I would install the bags,,I know when I did it took all the buck out of the ride,,made the truck feel 10 times more stable,,,and it is nice to drive a leveled truck...

I would install them. Mine sagged a bit, and the bags took care of it. They are easy to use, just add air. I bought a cheapo 12 volt made in chine air compressor to carry on the road to air up when I hitch up in the campground.

Thanks I may just do that. I have found Firestones for $260. Is that about the going price?

I am not at home right now I am on vacation in California. So I don't have any jack stands to use when installing them. Do you think I will need them? I have quite a bit of room to work under my truck.

I would also, they help alot. Get the Firestone Ride Rite Air Bags. It is $300- $400. Well worth the money.

I have the Arnott brand for about $250. They can be aired up to 100psi. That is way more pressure than you will ever need and it comes with a warranty.

I have the Air Lift brand air bags.
Empty I run 10 PSI, and with my 12K lbs 5ver I air up to 18 PSI.
If you want to save money, a bicycle manual air pump adds air easily. Five to ten pumps, (depending on pump size), is all you need to add air. Be sure to locate the fill Schrader valves in a location easy to fill at. I have mine mounted in existing holes that are in driverside frame just behind axle. Both bags filled from one location. Some have drilled out license plate holes and mounted fill valves through rear bumper.
You can always install a electric pump later if you thought you needed it.

My 2002 2500HD has the two stage rear springs. First stage is the 4 or 5 spring pack, and the second stage is the one very thick spring. Adding < 20 PSI with 5ver hooked up maintains the first stage springs engaged with the second, to provide a firmer ride. IMO, adding too much air disengages first and second stage, cause more sway or roll. 18 PSI levels my truck with 5ver connected.

I bought mine from a DP Vender below:

I installed the Air Lift bags on my p/u for towing my parents' Cardinal 34TS (pic in garage). They sure made a difference in the ride and handling. Before the bags, my suspension would compress until the bumpstops were about 2" from the axle. Now, I add air until the p/u, loaded, sits about 1" lower than it does empty. That's working well for me.
Price around. I found the Air Lift kit for $206 and change on Amazon, and Auto Anything in CA matched the price, plus a dollar. Both had free shipping. Since I live in CA, I went this route so I could pay the sales tax up front rather than having to deal with it when filing my taxes.

I run the Air Lift bags on my tow truck and wouldn't be without them. Nothing can help I65 from Indy to Bowling Green (except re-paving) but I couldn't imagine traving this road w/o bags and the ability to tune to the road and load conditions.

Sounds like a sound approach. Don't fill them to a point where they carry a load. Just add enough air to level the ride!

Honestly though if you don't want to spend a dime put water in the rear tank. Airbags can help with leveling but if you get that pin in the 5'er too high that will make it ride like worse crap! You will also notice that the tires on the rear axle are compressed more and are wearing more.

How heavy is your pin weight on the trailer? Do you have a front slide out?

To be honest with you I do not know what my pin weight is. I am on vacation in California from Tennessee so I am carrying a lot more then I would normally. So I can not get a good pin weight. Yes I have a front slide out..

Bags will make towing that trailer feel so much more stable. You don't realize it now, but after you install them the you won't be able to live with out them. They will take the wallow out of the suspension when going over variations in road and that harsh jarring that a 5th wheel makes going over expansion joints. Get the compressor too, it will save the hassle of finding one if you had to let the air out of the bags after you unhooked.

I found that JC Whitney had the best price on the Firestone air bags I installed 10 or so years ago, which are still working great. Never any problems, and they helped make the whole rig feel more solid. Two years ago, my son also found JC Whitney had the best price on the bags and a compressor.

Go with the air bags.
had them on my 2500 and they did wonders for handling and level.
You might have to play with them a bit to find that "sweet" spot for towing your specific load.
Have not installed them on the Dually, so far my camper only drops my back end maybe 2 or 3 inches at most.
