Summary: I have had Timberlines for 12 years now. My last one lasted 8 years, and would have lasted longer if I had not borrowed it to a friend who didn't use the groundcloth and pitched it on sharp rocks. I still use it for large gatherings with good weather (the floor was re-sealed), but I don't want to be in the BWCA and find out the sealant was perfect... :) The only thing that detracts at all is the clearly false naming of the tent.
Pros: Excellent construction: solid durable seams, tough floor, easy to set up
Cons: NA - even has the little things like mesh pockets on BOTH sides
Summary: We have been using the Timberline 4 in our Scout Troop for at least 15 years. They see more camping in a year than many tents will see in a life time. They are easy to set up, even for younger boys, and even in the dark. They can be backpacked, although there are better options, if the tent is split between two hikers. The zippers tend to be the weak point.
