Yes we would do it again, No problem with condensation between the panes, they were a $1300 option on our Redwood ordered Feb of 2012.
One of the side benefits as mentioned previously, no condensation on the inside on those cool morning. Previous rigs with single pane would actually pool water on the inside of the rig under the windows because it couldn't drain out the weep slots fast enough..
