How do I change rubber seals on my slides?

I have a 2006 3055RL Big Horn and it came with white rubber seals on all the slides. I've noticed the newer models now have black rubber seals. My white ones are really hard to keep clean and I want to convert to the black. Where can I get them and how are they replaced? Any help would be appreciated. My home e-mail is mhedlund@flash.net

You might check with Tom Atkinson as he had his changed out last year for the same reason. I think he had his done at the factory so you might call Customer Service and find out how much or PM Tom (Tom from Ypsi)
