I want to build a campfire in a building, is that possible and how would I do it. Second I want to create a bedroom is this possible?

First thing that came up when I searched "Portable Campsite" on http://newvegasnexus.com/ It says you can't set it up in a building, but this is still probably the best campfire mod out there.

You're going to have to elaborate on the part about creating a bedroom. Do you mean rearranging furniture and such? I'm not familiar with a mod that lets you do that, so if there isn't one, you would have to use the GECK to add or rearrange furniture yourself.
