I suggest a tent with the following...
1. A FLY. When it RAINS (and it will) and the WIND BLOWS (and it will), a tarp might not survive whereas a fitted fly will.
2. A sewn-in floor to help keep water out and to prevent
creepy-crawlies from any surprises. Snakes, insects, racoons, etc.
3.At least full standup height at the center of the tent. One has to stretch out those leg muscles in the morning or during nightly restroom visits or to change clothes.
4. Get your own tent stakes, not the ones that come with any tent. Toss them out.
12" steel spikes work well, to keep tent SECURE. See #1 above.
