I've been lucky on my shorter packing trips re: setting up my tent in the rain - I never had to. I'm sure that will not be the case on my upcoming thru.

So what techniques do folks use to pitch a dual-wall (body + fly) tent in the rain to minimize water/moisture on the floor until the fly is set up?

Single-walls or tarp tent do not (seem to) have this problem...but then they have the condensation issues. I am looking at some single-walls but would very much like some tips on setting up a double-wall in the rain. TIA. Cheers!
