The Timberlines and their relatives are GREAT tents that have succesfully housed folks for decades ...

... and therein lies the only real issue. They are VERY old technology and have poor volume to weight, since they are triangular. Dome tents are much more "semi-circular" which means that they have excellent space for the weight of the tent.

I recently read a book that said A-frames were fine if you're attending a civil war reenactment, but otherwise to avoid them.

By the way, one of the reasons Scout troops use the Timberlines is that Eureka makes individual spare parts available - or at least they used to. That is useful to troops when boys tend to leave parts - especially the small awning poles behind.

The earlier dome tents were somewhat limited by the technologies of the poles, but today's aluminum-poled dome tents are VERY strong and VERY easy to setup. One of the keys on all tents is to use storm guys if wind is anticipated - or even if it isn't. Storm guys GREATLY strengthen tents in high wind.

My advice would be to buy a more modern dome tent. Look for:

-aluminum poles
-clips to attach poles to tent body
-full nearly-to-the-ground rain fly
-vestibules over each door
-two doors (makes exiting easier, reaching gear inside easier, and provides a spare if one of the zippers jams)
-nylon or polyester floors - none of that plastic tarp material

Some recommended tents:

-REI Half Dome or Quarter Dome
-Alps Mountaineering Taurus (w/ aluminum poles) or Vertex
-Eureka makes nice tents, but some of the designs are overly fancy or odd (to me)
