Hello. I'm new here and I figure a few of you have a good idea of what the underside of my dream RV should look like. I've fallen for a lovely 92 Dolphin. It's the V6 3.L model with the 6-hole lug pattern. In the purchasing negotiation, I've had two mechanics take a look at the frame. The first (who admittedly IS NOT an RV kind of a guy) got all excited about the way the leaf springs were attached to the frame by means of a metal block (appx 3x3x8 inches) connecting the two components. In other words, the springs are welded to the block and the block is welded to the frame.) He was horrified and thought this had been jury-rigged mod to allow for the air-lift bags. Mechanic #2 likes RVs and takes a look. He says that's the way the things came off the line, and it's all proper and good. Other than this issue (or, I hope, non-issue), the truck has been meticulously cared for, drives nicely, and has repair logs. The house is impeccable. A penny for your thoughts? Thank you kindly.
