UL tents, being single wall, are colder and prone to more "visable" condensation.
By visable condensation I mean the kind that will eventually drip down the sides onto the floor, wipe on your head, or shower your head with ice in cold weather.
Double walled shelters are warmer. Generally the person is protected from draughts and breezes not picked up by the fly, bugs & critteres. The second inner tent (bug mesh, light duty fabric or heavier non-silicone nylon) usually has a floor. Condensation still happens, but is generally not "visable" to the sleeper.
A single walled tent only has a single layer of insulation. with no air space. A double walled shelter has an air space between the two tent surfaces, again, adding insulating value. This is, of course, offset by the need for ventilation. Soo you can only get 10-15C degree temp differential out of most tents. Single wall tents are usually closer to 5-7 degree differential. Roughly about twice as warm in a double walled tent as opposed to a single walled tent.
Staking is a problem with either. A good stake will hold well at about a 30 degree angle. The closer to a 90 degree stress on the stake, the stronger the staking pount, generally. Longer guy lines set near the top of a dome help more than those set near vertical tent walls. Wind hammer, gusts and vagrant eddies, will loosen stakes (a small elastic bungie will help minimize this and increase the effective staking angle.) Heavy winds will cause them to fail. I am ignoring poles and tent materials.
Double walled tents are generally used mostly by the light weight people. Those with less than 20 pound base loads. They generally weigh about 2/3 more than a single walled shelter. Cuben double walled shelters are rediculously expensive as of today. Single walled shelters are used mostly by the UL weight people, those with less than 10 pound base loads. (Note that this says nothing about the trip duration, nor, activities planned.) Per title, you knew that...
