The sixth annual RV Supplier Showcase took place this week at the Northern Indiana Event Center, with 141 companies participating. The event ran alongside the RV Dealer Open House and the THOR Dealer Open House. About half of the suppliers came from North America, with others from Asia, Germany, and the Netherlands. The showcase began six years ago in an 18,000-square-foot room with about 96 booths and a waitlist nearly as long as the exhibitor list. It moved to a 36,000-square-foot convention hall after demand grew. Show director Ryan Szklarek said the current manufacturing slowdown was expected after the COVID-19 surge in RV demand.
