Thanks to all who participated in the 2020 member survey. We received a good number of suggestions and encouragement about our current path. We have our dealer business survey underway and will extend the deadline for that to be completed through December 18th. We of course are looking forward to the results of that survey as well. The Manufacturing Survey will be released during early December for our manufacturing members and non-member manufacturers who are relevant to our industry. See results at the links below!
