Well Jon, as you enjoy the Anti-Squish Effect with your delightful classic, it also sounds like you have massaged out some of the Squishy Effect as well. Great to know that some simple things in life can bring us just rewards.
Does your coach have the front leafs or air-bags? Or by chance had it been upgraded to the air-bag system used on the 80's coaches. There was a independent guy who upgraded the suspension on quite a few earlier Newell's. He has long since been out of the business now, though it would have been nice if he was still around. I'm trying to recall his name and such.
