If you want the best tent without a weight concern, get a springbar. They will take a heavy Wyoming wind and keep you dry with lots of space inside. They will also last a lifetime. Too bad they weigh around 40 lbs and cost $500.

For backpacking you want aluminum tent poles (fiberglass breaks too easily) and fabric that won't leak and is light. You can luck out and find a tent around 3.5 lbs that fits this and is less than $50, but it is very difficult.

But, if you are only car camping, just buy any tent and throw a big blue tarp over the top.
