HydroTraxx was a line of amphibious vehicles made by SunLake Products, LLC. The factory was in Morristown, Tennessee while it’s corporate office was in Monrovia, Indiana. It looked like a widened Argo of the era, but featured individual hydraulic motors for each wheel. Both offered models were 6×6. The RAV6 featured a 35 hp gas engine, while the RECON a 35 hp Kubota diesel.
The first prototype was built in 1994. SunLake Products, LLC was founded on December 3, 2004 and was dissolved on September 11, 2013. Founding member Ralph L. McCleery passed away on November 16, 2015 due to an accident.
