I pull a Fuzion 393 loaded at over 18000 lbs and 3200+ pin weight with my 2010 2500 ccsb lmm. I put airbags in it almost right after I bought it. To be honest I almost never pull the 5er with air in the bags. If I do it is only about 20 psi. It sits dang near level with nothing in the bags. I've pulled quite a few miles in all sorts of conditions and never once have I felt overloaded or the truck not handled it exceptionally well. Sure a 3500 drw would handle it better, but so would a semi tractor. The fact is that if my trailer decided it up and wanted to lay on its side a drw truck is not going to stop it. I'm extremely happy with my setup.
