Looking for help in improving the ride on my RV

Thanks so much for the quick responses. I have a neighbor more mechanically inclined than myself (also retired with more time). I'm going to run the posts by him for his input and hopefully an offer to assist in the recommendations that can be done in-house. I'll post the results as soon as I'm done. I'm still waiting to hear back from the dealer who will be taking it on a test ride today.
