I’ve used a Big Agnes copper spur 3 for years backpacking with family, fitting 3 adults is snug but having a year old in between would be really doable depending on what you are using for the toddlers pad. Keep in mind taking young kids means you will be hauling all their gear too (as well as them at 1 year old) so saving weight on the tent is nice. While they do make a 4 person copper spur tent it’s a good bit more $ and I’ve found since we camp I primarily in the NC mountains where open relatively flat spots tent not to be that big… so finding a place for a 4person tent can be more difficult sometimes
Wait, what is their buy back? I've had so many BAs, currently have a Copper Spur 3 I split with my partner, It's awesome. This is coming from 20 years of a Seedhouse.
I have a BA Copper Spur 3. It's awesome, but I would want something more robust for your use case in the PNW if it's my only tent. I have a Black Diamond El Dorado if I'm expecting real weather in shoulder season (also used for ski touring). Love it, but it's single wall and not what you want for an only tent. People have mentioned a bunch above, and of those I'd probably look closest at Hilleberg (two different buddies own and love) and Slingfin. Can get pretty weight competitive with lighter options, but much sturdier in weather.
BA Copper spur 3, Nemo Dagger 3, MSR Hubba 3 or REI Half Dome is what I use
I love my copper spur 3 for backpacking and kayaking trips. My wife and I like a little bit of elbow room , so we got the cupper spur 3. We have a ton of room for 2 people but at the same weight as many other lightweight two person backpacking tents.
I've loved both the Copper Spur and the Hubba Hubba - both have a 3 person version if you want more space. I've never had a problem with water pooling on the copper spur, but that maybe either a difference in the yearly model or maybe user error. I did have it sink down from snow weight once in the Tetons, but I just woke up and pushed up on the ceiling and it all slid off and I went back to sleep without even getting out of my sleeping bag.
