Hi Aaron,
I do plan on using this tent for my kids. I have 2 teenagers, 1 toddler, and a new born now. I have slept in the SL-5 with my 2 oldest, and there is plently or room for 4 adults to have a lot elbow room. 5 adults could fit easily enough too. I will primarly use the SL-5 with my wife & 2 youngest. My older 2 are only here in the summer and now girlfriends, part-time jobs, and other things will probably keep them from camping with me. I wanted a shelter to use on our family road trips so a larger tent was in the plan from the start.
My plan on this tent was too have a shelter that: 1. had wiggle room for a rainy day. 2. sturdy set up so that a bumped pole wouldn't drop it. 3. enter & exit w/o rain or snow getting in. 4. reduced ammout of guyline to reduce tripping hazard for kids. 5. bug proof! hey it's our family tent. 6. well venting, kids can really heat up a tent with their yelling, fits, and playing. 7. have a big enough vestibule for wet gear 8. enough room for a cooler (when not in bear country) and game playing…just for those time when waiting out weather. 9. light enough to use on short overnights.
So I had a big list of what I wanted. I have used mostly Golite shelters in the past, so I knew I liked the heavier silnylon used in their shelters. I have never exerienced rain misting in any of my Golite shelters. The robust floor of the nest was another factor with kids. The seems are taped, and the upper vents are nice and big. The SL-5 is tall enough for my wife to stand up in it, and the square footage is large enough that my toddler can run around in it!
I hear ya on the free-standing mind set, I was thinking about one myself. What I didn't like was thinking about expensive carbon fiber poles getting stept on my kids. The Golite pole is very stout, and could withstand the weigh of a child easily…IMO. That timberline is one great tent! I used them in the Boundry Waters on a couple of trips in the earlier 1980s. There is a lot of floor space in the SL-5, so you can put you kids far away from the support pole to prevent any kid pole interaction during sleeping. One downside is that it takes real estate to set up a tent like the SL-5, or the tarptent Hogbag, MSR Mother hubba, ect.
Wow…did anyone really read all of this crazy long post? If so…I bet you are tired of reading it because I am tired of typing it! lol! I hope this help you out Aaron, and good look finding a shelter that work for your family.
