Locus Gear - Khafra DCF-B

I have used both a triplex (on the GDT with my wife and baby) and a locus gear khafra 4p mid tent for a LASH on the PCT (with wife, 4 year old, baby).  Not the same age as your family but honestly I think the older kids will be easier.  The triplex is nice having an integrated bug net. It's spacious. It's also a pain in my opinion to pitch. But at least you can open the vestibules and get some breeze. The 4p mid was roomy. I made a perimeter net and a floor of my own. The weight was the same as the triplex and the footprint more or less the same. But having a perimeter net, if you open the door for ventilation there is no bug protection. it has bomber head room though.  You can get a full inner for those tents. Those are just heavier than a perimeter net. Also look into tarptent options.  All depends on your style and objectives.

This is true and I'm not sure what the typical lifespan is of DCF but I've had my tents last longer than this with somewhere between 0 pinholes and two.  My duplex - at least as many nights as yours. Zero pinholes.  My triplex - similar nights as duplex. One pinhole.  My Locus Gear Khafra - 0.5 oz DCF - bought used with unknown life before. Used by me so far for over 120 nights. Two pinholes.  Not sure if they are from the material degrading or from incidents. They are easily patched on trail (way easier than silpoly IMO) and our holes haven't shown any progression or escalation. I get a hole. Patch it. That's it.  But I don't know how my experience stacks up to others. Just wanted to put it here for reference for others looking at this 

>I don't know of any single-pole design that would perform better MLD Solomid/Duomid/Supermid HMG Ultamid 1/2/4 Locus Gear Khufu/Khafra Black Diamond Megalight Oware Pyramid Basically any single pole traditional mid with steep sides will do better with snow loading than the two pole and asymmetrical mids.
