I certainly didn’t see cracking in the leaf springs nor could I tell it was sagging. Had someone follow me in a car and could not see a problem nor feel a problem while I was driving. I sold the RV and mentioned that it might need new shocks due to 50,000 miles. We never upgraded the suspension. The factory shocks and steering stabilizers worked just fine for us. I thought because it was a short RV but our new 26’ Minnie is just as stable on the highway. But I’d like it to be a little higher. I can hardly get underneath it especially under the battery compartment in the steps.
