Rei passage 2 weighs 5lbs 5oz, not sure if that includes foot print but I don't think so. That was my first backpacking tent for 2, now it's my go to car camping tent, a great tent tho.

Get a lighter tent or tarp. I currently have big Agnes ul1, I just take the fly an footprint and that's super light.
