Wow, a Quest tent! Thats sort of an antique. I reviewed Quest tents a few times for the Outside magazine Buyers Guidethe Viper, as I recallbut havent seen one in a store for years. My understanding is that they quit production three or four years back.
Sierra Designs Asp 3
Asp 3 Tent
But, yeah, I see your point. You want good ventilation, and you want it even when the fly is left on the tent. The main thing you need is a tent with two doors, either on the sides or front to back. That way, you can try to aim it into the prevailing breezes when you set the tent up, and get some flow-through ventilation.
An excellent example: Sierra Designs Asp 3 ($369; sierradesigns.com). Its a three-person tentreally roomy for twothat has a canopy entirely made of mesh on the upper half of the tent. Plus, it has a big vestibule door that takes up much of one side of the tent, and a slightly smaller door on the opposite side. Open both up, roll back the vestibule and tent fly over the doors, and let the breezes flow. Then in no time you have complete shelter should the T-storms hit. Its very light (about six pounds), in case it needs to go into a backpack at some point.
MSRs Mutha Hubba ($399; msrcorp.com) is also a three-person tent with lots of ventilation. Its canopy is almost entirely made from mesh (just a small strip of ripstop across the top). And big doors front and rear again give you lots of flow-through ventilation. Its a little bigger than the Asp 3 and weighs about seven pounds.
If a three-person tent is too big, and the $360-plus price tag a bit steep, take a look at Marmots new Bise ($269; marmot.com). Its a great shelter for two, with doors and vestibules on each side. That makes it really easy for someone to get into and out of the tent without disturbing his or her companion. Plus, with the vestibules tied back, its almost like sleeping completely outdoors. Molto ventilation. And its a very tough little tent, so you can manage storms easily.
Lastly, REIs Quarter Dome UL ($219; rei.com), offers a very similar design to the Bise at a very compelling price. Like the Bise, its a two-person tent, and each camper gets a private vestibule and enormous door. Keeping cool is easy. And so is keeping dry.
Hope that helps! Happy camping.
