Tacoma RV in Fife, WA should be able to handle any warranty issues you may still have.
I found this using the "Dealer Search" page on Travel Lite's website, using one of the several ZIP codes for Seattle, WA.
Frankly, I'm calling shenanigans here. We've gotten the "I'm a helpless woman" thing twice now. C'mon, it's the 2010's. There's no such thing as a helpless woman anymore, especially when it comes to complaining to a manufacturer about shoddy workmanship.
If you're really having issues, go on the Travel Lite website, get the phone number, call them up, and read them the riot act! You can do it.
