Can a high end Spartan K3 Chassis be better than a Prevost?

What I do know is that my '88 Prevost is still going strong. It has an aluminum and stainless steel exterior with just fiberglass caps. No peeling, cracking or delamination issues No, it's not prefect but it still gets me from place to place, replacement parts are still available and I can pull into a Prevost factory services center at 5 or 6 locations around the US. I full time on business so I have been living in it since '99 and have over 350,000 miles on the coach.
