Why don't you check to see if Firestone makes some helper air bags that will work in conjunction with the stock coils? I've used them on my Dodge Ram and they work really well. Obviously, that is a leaf spring truck. 3/4 ton coil springs would probably do it, or some HD variable rate springs, but you are always going to sit higher in the rear when unloaded than you probably would want. Can you load the trailer to reduce the tongue weight somewhat? I'm sure you are using a weight distributing hitch.
