Mine sits on the overloads and I'm going the route of adding two extra springs on each side. I did the same upgrade to my talocoma in 2000 for carrying a contractor heavy cap and that worked great and I still have it. The place that did my lil truck is in Michigan and a quote from them on my ram 3500 is about $450.00 which is about 1/2 what the closer ones closer to where I live in Virginia cause they were over $800.00 The place in Grand Rapids is a block from my parents home so I get to visit. Anyway I thought about stable loads but I believe the springs will give much better control with my TC when I put a 48" extension on to pull my 24' enclosed car hauler. Just my .02 cents
