Jack,
It's not just the RV industry with issues, right now I've got some major HD truck component suppliers with 16-18 week lead times for products that should be setting on their warehouse floor... and many others with order fill rates running around 80% or less. Many of the same brake, suspension and drive train components are used on our coaches. The just-in-time mentality of the major players has created a tremendous backlog for both the OEM's and aftermarket. As the sales increase, OEM's are not able to project sales as the market needs increase and don't want to warehouse additional product while they retool manufacturing. It's a catch 22 right now.
