lance camper porpoising and tires cupping

That's what I was wondering. I had heard it was no longer in production, but saw it brought up in this thread. Normally manufacturers copy one another when something comes out and no one copied this idea leading me to wonder. Was Lance the only one with this problem or did Lance simply offer a placebo to cure an issue that had more to do with the road than the camper.

I'm sticking with "you can't fix the road" as where there will be a problem is pretty easy to predict based on expansion joints in concrete and in Interstate close to major cities that carry a lot of traffic and are showing their age.

My two cents
