Welcome to the forums and congrats on your new Raptor.
Probably, a good starting place some of your 'up front' questions about your new raptor can be found on good ol' YouTube.
Click here. I did a YouTube search on 2008 keystone raptor and these videos came up. Also, YouTube has a LOT, I mean, a LOT of videos on virtually anything RV related. Just type in the YouTube search box and be overwhelmed. YouTube is your friend!
Also, this forum is a good place also for specific details you may need answered too. Eventually, someone will come along and have the answer you need.
Enjoy that new Raptor and hope you have many, many great camping adventures with it.
