Two options... I have used this Coleman tent for 5 years and still like new. 4 person. anything smaller makes it too crowded and it takes up the same space as a 2 person tent. Has higher ceiling than a offbrand tent and be sure to get the rainfly like this so it breathes.

OPTION #2.... A hammock which takes up almost no space. One with a mosquito net and extra long. My brother uses one of these for week trips on the Blue Ridge Parway & the Smokeys. Goes hiking to the mountain tops for days. Says very comfortable and will never use a tent again. No need for sleeping bag and all the extras.
