2016 FOREST RIVER CARDINAL Unknown Or Other Problems

I CANNOT FIND ANY INFORMATION ON MY FIFTH WHEEL TRAILER WHEN ENTERING THE VIN ON MULTIPLE WEBSITES. THE ONLY THING I CAN FIND IS AN INCORRECT LENGTH AND AN ERROR CODE SAYING THE MODEL YEAR FOR THIS VEHICLE MAY BE INCORRECT. I AM TRYING TO RESALE THIS TRAILER AND I AM HAVING A DIFFICULT TIME DUE TO THIS. IF YOU LOOK AT A 2015 BROCHURE OF CARDINAL TRAILERS, MY 3450RL MODEL IS THERE. IF YOU LOOK AT A 2016 BROCHURE, MY MODEL IS NOT THERE. MY TRAILER IS A 2016 3450RL, HOWEVER, I DISAGREE. I DON'T KNOW IF THIS WAS A SHOW TRAILER AT SHOWS OR WHAT THE DEAL IS, BUT I WOULD HAVE LIKED TO HAVE KNOWN ALL OF THIS BEFORE I PURCHASED THIS THING NEW AT AN OUTRAGEOUS PRICE. I AM SUPER UPSIDE DOWN ON A 2016 TRAILER NOW. THIS INDUSTRY NEEDS REGULATION.
