Welcome Junglecat. You sure are pushing your limits with a trailblazer. Sure hope you fair well once you get your cargo loaded up. Use caution!

As for the slideouts, as already mentioned your manual should give you an idea where/how to manually slide them. When we bought our Keystone it also came with some attachments for a power drill that were included with the manual. If your dealer gave you packet of paperwork, look in there to see if you have anything like that. Not sure if Bullets have the need for those. Apparently our Passport does.
