Air Bag questions

[jays68yak]

I would like to tow a car trailer with my suburban. It is only a 1500 and has rear coils. I would like to at some point down the road bag the whole truck. Could I just bag the back, but use all the parts that I would one day need for a full system? Where can I get the rear bags that will bolt in place of the coils? How much am I looking at to do just the back? With at least 2600lbs bags if not bigger. Compressor, line, tank, bags....what would it be? Im broke as of now so its not going to be anytime soon, just wondering what im looking at.

You can mount 2600# bags in place of the coils for now w/o having to get the whole system if you dont mind manually filling them when you add a load. The bags, DOT air-line, & misc fittings, delivered to my door was about 300$.

For my beater (1/2 ton swb that hauls my 18ft car trailer), I mounted the bags & ran air lines w/schrader valves to the license plate box. I typically ran around 30psi when not towing & then just bumped the pressure up to 60psi w/the trailer hooked up (I just carried a 7gal air tank in the trailer). I used this set-up for almost 2yrs & the only problem I had was it's very easy to 'tweak' the schrader valve when filling (once it's tweaked, it won't allow you to fill).

I started using my trailer weekly a while back, so I went ahead & purchased the compressor/tank/controller set-up because it sucked to have to air it up in the dark before going to work (that's when I was most likely to tweak the valves).

Where is a good place to get good quality cheap bags? Will all of them bolt where the coils were? Or is the some special ones?
