business pages can't have "friends" they can just have "fans", or people that "like" them.
when you want to post something and tag Phoenix, here's what you do.
1. Visit the Phoenix Cruiser RV page on Facebook, and "like" it.
2. Place your photo in your "What's on Your Mind" box, to post it on your wall.
3. In the text box along with that, type your message, and be sure to type this: @Phoenix Cruiser RV's As you start typing, a little drop-down will suggest "Phoenix Cruiser RV's" to you. Select that to change the @Phoenix Cruiser RV's to a link to the Facebook page.
4. Change your permissions for this post from 'Friends' to 'Everybody', and submit it!
It will post on the Phoenix Facebook page, and will post on your wall. Your friends will get the update from you, and they can click through to the Phoenix Cruiser page too if they like! :-)
Cheers!
