I am considering adding air bags or suspension to a couple of my work trucks (DA 2500 CC's) but I still have not found enough information or personal experiences with this setup. http://www.airliftcompany.com/ROADTAMER/c3500.htm. Anyone have any personal experience, pics or other with regards to this setup?? It looks like a strong/reliable product but I am curious why I have not seen anyone with one of these setups. Thanks for any info.
