Welcome the the "Challenger Owners Club." No rules - no dues. Even when you think you found it all - something new pops up. Not sure if it still a feature - did you look under the middle inside step? Join "Thor Challenger Owners Unite" at RVillage to keep up with Challenger owners travels and meet some that are near you or even in the same park. We have been enjoying out KT for two years now and couldn't be happier.
