Sportsmen 3554

Hello all, My husband and I have currently own a 2004 Sportsmen 3554. We are looking to upgrade, but cannot find the value of our rv in the NADA guide. That particular model is not even listed in K-Z's brochure. Any suggestions?

It is a Fifth wheel. I have looked at their website. They do not have a floor plan for the 3554. When we bought the rv, the dealer had brochure for that model year and it was not even listed there.
