I am wanting to order a 2" lift for my 87 GMC SWB 4x4. I will ne towing a trailer/single car hauler. I was looking at rough country and read a lot of positive reviews about tough country. Question, many here advise that tough country is a softer ride. If so, maybe the springs are not ideal for towing? Any suggestions? Prefer to do full suspension (new springs in front and rear) Or...how about add a leaf? Could do this as well and get the 2" height wanted while increasing payload I assume.
