User Review: Eureka! Timberline
Design: 3 season but holds up well during even heaviest snow
Ease of Setup: very easy after the first time, you can do it with your eyes shut. Time yourself sometime - you'll be amazed at how quickly it goes up
Weight: 6 + lbs
Price Paid: shop around - $99-$300
Have had this tent since 1977. Been through torrential rain, snow, heat (have thrown the worst at it). Never any problems whatsoever. Sleeps two fine, but cramped with gear.
Excellent heat retention in winter, never froze even at 12k+ feet in the eastern sierras. Lightweight and easy to arrange on the backpack. Highly recommended.
