A small house!! By the sounds of it some people want a full size barn for a ten!!
For years I carried a MOSS Big Dipper for 4 - a great 4 season bomb shelter of a tent (the Mount Everest expeitions use this same tent). This tent will take 100 mph winds and several meters of snow - it was great for my wilderness canoe adventures in the far north and winter camping. However, I found this tent too big to carry on the bike.
Last year I purchased an MEC Wanderer 2 Tent from Mountain Equipment Co-op. This is a small, very light and compact, yet very strong tent. My wife and I did a 17 day trip of the east coast of Canada last summer - two-up on my new bike - carrying all camping gear - tent, sleeping mats, sleeping bags, stove, dishes, pots & pans, food - plus all clothing including rain gear - on the bike - NO TRAILER. (By the way - I am not a small guy, I am 6'4" 250 lbs and I fit very well in the tent with the wife)
Being an avid wilderness canoeist - who frequently portages further than I paddle - I know the value of light weight compact gear. I don't want a monster tent that takes me 20 minutes to put up, or blows over in the slightest breeze, or has all that wonderful roof and floor space to spring leaks.
We camped on the Outer Banks of North Carolina last summer. Every tent in the place blew down - but not my little Wanderer - it stood fast.
I highly recommend MEC (Mountain Equipment Co-op) for your camping needs - look them up online. 1. It is a Co-op, so it is non-profit and any money it does make goes back to the members, 2. membership is only $5.00 for life, 3. ALL products are guaranteed for life with a no hassle exchange policy 4. for our American friends the Co-op is Canadian so you are using Canadian vs American dollars, 5. they sell great gear not cheap Walmart crap - good gear is actually much cheaper in the long run. 6. they do sell a few barn size tents as well for those who insist on performing circus acts inside their tents
