air bags or x-tra springs?

[MxerChris]

forgive me guys but this on a ford f-350 chassis, let me explain, I've gotten into a great side job with a production company filming high school and college athletics down here in the southeast, last weekend I worked audio at the ESPN plus game at Troy st. its alot of fun and great pay (bombing money) now back to the production truck, its a f-350 chassis with a van front end and about a 12' box (we call it the potatoe chip truck) loaded with electronics and has 3 A/C units on top, very top heavy and the thing sways alot. once it gets to rocking side to side it takes a while for it to stop. first I told them they need a good heavy duty set of shocks, and a set of air bags or leaf springs. which do y'all think would be better? I'm open to any suggestions. thanks, Chris... ... ... .....

If the van already has.....

overload springs, it may be the cheapest to add another leaf (or two) there. If not, air bags would probably be the cheapest. One thing to consider, the simpler the better. These are not going to be a bunch of guys and gals that are "into" maintaining the van, just driving from point A to point B. Air bags could develop a leak and then there is a repair bill (and down time) somewhere along the road when you are in a hurry.

One thing about the airbags, if they are installed so that each bag can be filled independently they will help with sway quite a bit, but if they are installed so that they are both filled from one air fitting they won't do much to help with the sway problem you describe. I have airbags on my truck, but I am also willing to deal with the potential issues that they bring with them (leaks, etc. )



For your application it's hard to say, and being non-car-people a set of rancho 9000's set real stiff may be a more trouble-free option as far as not needing any attention.



Good luck,
