I am in love with this design! Lived in it for 6 weeks while traveling around the PNW. The 4 meter was large enough to have an XL cot, table, wood stove, & chair with space to move around still. When I didn't need the wood stove I had plenty of space for yoga.
It was easy enough to set up by myself (smaller woman) and I loved the extra porch area that the star bell provides. It creates more protection during the rain if you want to have a door open for air flow and a dry door mat. Also, the way that the rain fly is pulled out with each 'star leg' pulling the water further away from the tent so it doesn't pool next to the tent base. I did opt for the extra rain fly which keeps it cooler in full sun and dryer in heavy rain. I was glad to have it!
If I was keeping it setup longer term I would splurge for a larger tent and the tripod pole. It might be difficult to find ground space while traveling with that larger footprint, hence why I opted for the 4m.
Loved the fact that I could take the vinyl floor off for a deep cleaning after my trip. Also, having the full 360 degree mesh made such a huge difference during the warm weather for air flow.
