We have been very pleased with the Lunar Duo in most respects…especially volume. Interior footprint is 90″ x 54″. So a wee bit wider than typical 2P shelters. Coupled with the vertical side walls, it feels very roomy. No matter how much I preach to the Mrs about paring down, she always seems to have an inordinate number of stuff sacks with…well…”stuff”. So the Lunar Duo’s interior dimensions seemed to have worked well for us. There’s the typical re-tensioning, re-adjustments of stakes once upright, which can be a pain sometimes in rocky settings, etc. Having to open the tent up while on the ground to insert the ridge line poles is a pain, especially in the rain.
I didn’t realize, however, how much I missed the ease of setting up a self-supporting tent until we saw a deal at REI last year on a 2P Copper Spur. We took our EXPED Duo pad and EE Accomplice quilt to the store, set the tent up, tossed in the pad and quilt and climbed in. The CS 2P dims are 88″ x 52″ (head) / 42″(foot). Interior walls are near vertical. I thought this would work but it seemed claustrophobic compared to the Lunar Duo. We rarely use the pad straps with the quilt so the quilt spreads out a bit. In the CS, the quilt was right up against the side walls…maybe due to the extreme taper to the foot end. 2″ less at the head end seemed fine but that 42″ at the foot end seemed to make a huge difference. Even taking into consideration the taper of the pad. Maybe its just me. FWIW, we looked at the 3P CS and the overall footprint, for me, is just too big. We’ve already run into plenty of situations where finding a suitably large enough spot for the Lunar Duo was tough. And it looks to me like the 3P CS would not be very wind-worthy.
The ease of setup was great though. The Big Sky Revolution 2P interior footprint is 91″ x 53″(head) / 47″(foot). Side walls appear to be near vertical. I’m wondering if those extra few inches will be enough. If so, being able to pitch fly and inner in one go would likely seal the deal. I can deal with pegging the corners down (less guess work with the Big Sky vs the Lunar Duo) and putting out a few guylines.
I’ve looked at dims on offerings by BA, Nemo, Mtn HW, MSR, etc and while close, none seem to be quite what I’m looking for. Thoughts? Have I overlooked anything?
