If you go to Jayco's website, on the bottom left there is a "Archive" link. You can view the 2010 brochure and the manual there. I think our 2011 model has a slide out about 10 ft long, but of course it is in storage too. I do remember the awning is 16 ft. All other specs should be in the brochure on their website.
