I use one of the survivalist caves in Zion, as I absolutely adore the place. As Waking Cloud said, it's peaceful there, and thats something my Courier can really use. Really, after everything in Vegas is done, she'd like nothing more than to hang up her armor, set down her rifle, and take Cloud up on her offer to stay in Zion for good.
Sort of this, my one character who is survival/melee/unarmed focused would enjoy it, and Waking cloud said about finding peace there I think my character could do that. Besides that character sort of looks up to Joshua, and I can imagine Joshua staying in Zion.
I wish there was a new perk in HH we saw "home on the range" step in the right direction, we can sleep at campfires, but for me I would like the option of setting up a camp. Dont know if it would be possible but your camp could even be a location on your map you can FT too.
I just wish I could set up place in zion, looks great, but I dont want a cave, but I need something practial.
