Keystone does not supply an owner's manual that is specific to any of their RV's. The manual that is provided is a general, generic one that applies to all models of that year. The manual is revised every so often but you won't find any information about switches or any other such details.
If you go to the Keystone website (
www.keystonerv.com) you can download recent manuals there.
If you bought your Avalanche from a dealer, you should have been given a walk-through by one of the techs showing you "all of the switches and whatnot". If you didn't and want to ask questions here, please post them in the appropriate forum as this section is intended for new members to introduce themselves and to be welcomed by existing members.
And welcome to the group!
