cool, all sounds good.
I leave gear (but never food) in a tent all the time on climbs, never personally had any problems.
Occasionally one hears of a marmot (or Pika) chewing through a tent to get at stuff inside the tent; they really like chewing up stuff with body salts on them. In very heavily used areas where there tend to be tons of marmots, I occasionally empty the tent, put sleeping bag, mattress and other "chewables" in a sack and hang it from a nearby tree branch. I also leave the tent door open and tied back so the critters can get in and see there's nothing of interest (vs. chewing through to find out!). I would definitely not leave any food in the tent, of course. Since you're not spending a 2nd night, why not just pack up and hang all your overnight gear and extra food.
