Do you have any recommendations for a survival/crafting heavy run of Fallout New Vegas?

I think I only used crafting a few times in NV and it was likely for an achievement or because a mod required it so I was thinking about doing a crafting focused play through.

I think I'm going to focus a bit more on the survival aspect as well. I've played on hardcore mode before but because Nuka Cola reduces your tiredness and last time I was using the cannibal perk and didn't have to worry about food I think I missed out on the true hardcore mode experience.

I'd appreciate any tips. Maybe some places to check out to get recipes or things for crafting ammunition for example.
