am planning a long tour and have seen the vaude taurus ultralite tent (2kgs) which i like. it has a small porch for cooking in and as a 2 man tent its big enough for 1 man and gear. have also seen the cycle specific tents with a porch big enough for the bike. it weighs 3.5kgs. Is the weight worth the "security" of hiding your bike in the porch? any comments please.
