This Chinook 18KLE RPM Extreme was purchased in April 2021. It has been kept inside a climate controlled building at my home. The RPM Extreme denotes that this unit has 100 gallons of water capacity as well a 40 gallon fuel station. I have added a flat screen TV as well as a unique generator stand that is mounted on the Trailer tongue. I towed this unit with a 2019 Ford Transit van EXT with no problem. The rear fold down ramp area also has a rollup precision fitted canvas cover with clear windows as well as canvas covers over the vinyl windows. The rear deck can be positioned in a level fashion with cable adjustments if you wish to have a back porch. The tires show no wear and the suspension rides smooth.
