Welcome and congratulations on your Bay Star!
We purchased our coach new and had what I think is a fairly typical first year experience with working out bugs and making a list for our end of warranty visit to the mother ship. Other than those issues, which were really pretty minor, we have greatly enjoyed our unit.
We have had no issues with the chassis and have found the F53 to be very reliable with plenty of power for our use. It doesn't ride like a DP and can get a tad noisy on climbs, but not anything that has detracted from our enjoyment.
Safe Travels!
