Help with hitch, Airbags

We just purchased a new Excel 37SDF GVW is 18,750, pin weight is listed at 2800, (im sure that is conservative). Our truck is a 2012 RAM 3500, Dually,CrewCab 4x4 , 4:11 Rear. We pick our 5er up in 12 days. I need to get my truck set up. I was looking at getting a Reese Elite 25 K hitch with underbed mount. I was thinking I need Airbags also, Can someone give me advise on an airbag Brand to get and what they think of my hitch choice?

I think the Reese 30035 rail kit would be fine, but if you want it all hidden, then the Elite would be good too. Rails don't bother me.
What is the GVWR of the trailer? You want a hitch with a higher rating than the GVWR of the trailer.
You don't "need" air bags. Hook up to the trailer, see how it sits/rides/etc. Then decided if you "want" them.

Air bags dont add to payload capacity. But I have Firestone Ride Rite's on my 3500 Dodge HD. They make a big difference in controling body roll/tilt and make for a nice solid feeling and limit suspention jar or jolting over those nasty interstate bridge humps/bumps and lumps.

Extremely conservative. Pin weight of that heavy a 5er will probably be between 17 and 20 percent of gross trailer weight. Count on 20 percent of GVWR, then hope for 17 percent.

With a GVWR of 18,750, you can expect wet and loaded weight to be about 18,000 by the middle of your third RVing trip. 20% 0f 18k would be 3600 pin weight, so that's what you should plan on. Then if it winds up as only 3,060, you'll feel really good about making such a smart purchase.

Great choice for a hitch for that monster-size 5er. Check online prices for both the hitch and the install kit - especially ETrailer.com and reese-hitches.com, and I always check Amazon.com - just in case. Then if you decide to have a local shop do the install, at least you'll know how much they are gouging you on the parts.

By far the most popular brand of air bags for the rear suspension is Firestone RideRite.

Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 3.5L EcoBoost SuperCrew.
