Love bug season usually starts in September.
I always put a tarp under the tent and a smaller one inside the tent. I pull each corner together to form a tray and secure with a clothes pin. That way if water gets in, it goes under the "tray floor" and our stuff stays dry. We use cots, with the stackable plastic drawers for clothing and our shower stuff is in buckets or kitty litter pails and goes under the cot. I have been known to put a tarp, a shower liner, or plastic tablecloth over the beds in case of leaks.
I second the screened dining tent. I have a folding table with a folding luggage rack under it as a "pantry." This keeps the table uncluttered. In the pantry, i use see-through plastic bins with tight-locking lids to keep out bugs, critters and rain. One holds long handled utensils, another holds paper plates, napkins, zip lock bags, etc. and one has spices, cooking spray, and so forth. While I am cooking, I may slip the lids under the bins so I can just grab whatever whenever it is needed, then when finished cooking, I make sure to snap all the lids back on. Some of my bins are smaller and most of them stack on same-size bins.
I also have a utensil rack that clamps to the picnic table and has a small shelf for salt & pepper, a garbage bag holder, a paper towel holder, a hook on top for a lantern, and several "arms" that branch out to hold a pancake turner and long handled spoons and forks.
I have a picnic set for the table holds eating utensils, catsup, mustard, salt & pepper, and paper plates. I have a small table-top plastic stackable 2-drawer thingy that I keep such things as corkscrews, candles and lighter, toothpicks, steak knives, playing cards, etc. in (things you might need at the table sooner or later). All the kitchen stuff stacks on a large shelving unit in the garage and can just be loaded into the RAV4 when time to camp and unloaded onto the shelves when I get home again.
