Need some advice on which 5th wheel units are "high end"?

There are a lot of used Excel and Nu Wau units in the midwest as that where they are made. Our older Excel is near top of the line. 80% of repairs to RV's are appliances. Excel builds their units entirely online, including frames, oak woodwork and furniture. The newer stuff is not near the quality from the big guys. Buy a used unit and save your money to keep it working.
