In my new 2004 3685 the seals that are between the slide out and the interior wall are different than in the old unit (2002 3655) in the old unit there were very thick white padded seals aprox 3-4" thick...the new one is not the same..There was no option to order anything like that..I do have the artic package and all of the bells and whistles, so if it's an upgrade, it should be there. My question is anyone familiar with this?...Just want to make sure I'm not missing something I paid for. The seals in the old unit appeared better due to the size, but with new technology, maybe the small new thin ones are just as good. The new ones are so small you don't really notice them, the old you couldn't miss them they stuck out so much.Part of me thinks this is an improvement...the other part is wondering if I missed out on something.
