Springs or Bags

[marcindy]

I know this has been reviewed before, I have read through the comparisons between adding air bags vs adding springs. I'm hoping to get some advise here.
We just picked up a 2015 2500 GMC denali duramax along with a Open Range 308BHS, hitch is Equalizer 4 point 14k. We mostly dry camp, so I have 3 Trojan T1275 batteries, 80lbs or so each. I haven't gotten a chance to scale it yet, I moved the bars up one notch from how the dealer installed it, and now the truck sits level (within 1/4") front to back- the back drops 3", front is almost unchanged. For now, I estimate tongue weight is 1200lbs.

The back end squats more than I thought, and thinking of either installing air bags, or adding a spring. I have read mixed reviews on both. I'm hoping to hear from folks with either experience, and what brand/product used (like firestone, etc) pros/cons.

I'm in no hurry as it tows "ok". I'm leaning toward adding a spring, but open. Mostly concerned with ride quality.

Thanks

While the experience was on my prior Silverado 1500, I am a fan of the Timbrens. Low cost, no maintenance, easy installation. If (when!) we move to a bigger trailer, if extra "support" is needed, I'll consider a set for my 3500HD.

I have used airbags for my tow vehicle for years. It really does help.

Does Torklift have Stableloads available for your truck yet? There are two versions.

With a travel trailer, a correctly set weight distributing hitch should let you level the truck and trailer without bags or helper springs.

I've had Firestone bags on 3 gmc trucks now and won't tow without. No slamming on the rear overloads/ bump stops as you go over large dips. More of an air cushion effect. I think it is telling that manufacturers are moving to full air on some models. An extra spring will work but zero adjustment.
