Safeguards would include verbiage like; no grills, candles, open flames, ect.

, grill, grill tools, throw blankets, throw pillows, board games….to name a few. 

You should certainly plan on coming to the monthly meet ups, which are the second Wednesday of the month at Pearl Street Grill downtown.

That's a giant red flag for that grocer potentially declining to renew their lease, vegan gluten free customers don't want to walk through a cloud of cigarette smoke to get to their ethically sourced non-GMO organic avocado, and obviously the "no smoking within 50 feet" sign is going to be ignored by the customers of that neighboring business, who are all a bunch of smokers.

"As a non-smoker I can tell that someone has been smoking in here..."

While you mentioned they would be primitive, you may still need to clear and level the sites, provide fire pits or grills, and establish basic sanitation facilities like portable toilets or a designated area for waste disposal.Accessibility for Campers: Making the camping areas accessible for campers and overland vehicles can broaden your potential customer base.

But having a natural gas grill would be a big liability right?  

Smokers aren't a protected class haha.

Unless you are doing all of the maintenance yourself, figure about 5k yearly for touching up paint, repairing misc. items the guests break, bikes, kayaks, BBQ grill, pool maintenance, lawn service, pest control, replace TV remotes every time someone checks out. 

I don't think anyone could be evicted simply because they are a smoker but only if they violate the rules that are set.
