fair points about wet ground. I’ve got an MSR Hubba Hubba that sets up in about 3 minutes, 5 if I’m taking my time.When I've played around with the RTT's, they setup way quicker (especially in adverse conditions). A friend has one and it's basically 3-4 minutes... regardless of sunshine, rain, wind, or "OMG I can't feel my fingers".
Really, the only part that takes any time is the little posts for the fly.
His also didn't have to deal with sitting in the soggy mess after all of the rain.
But, his tent also cost $1,800.. mine was $150.
there are faster tents
