I can 100% support this as my dnd group decided to go camping last week.
I actually quite like doing this. Though I might be one of those crazy guys (no, really?) that actually enjoys camping. As long as you don't get smoke up your eyes, the scenery is awesome for setting the mood for a campaign.
If asked the question "how can I do this within this system?" answering with "use a different system" is never a helpful or appreciated answer.
