Thank you, Mark. Some good tips there. Why haven’t you used yours in years? What has been your replacement?

	We haven't used ours in years but we used to use it on multiday trips.  I believe the foam insulation is thicker than most coolers and it is in a convenient spot.  Never used blocks or bags of ice I don't think.  We have tons of those gel ice packs.  We also have a digital thermometer with an "outside" sensor on a long wire.  We put this in the icebox compartment to monitor temperature to prevent spoilage.  Don't recall any condensation issues.  I believe anything draining from the icebox drain will go to the bilge which is generally considered an acceptable reservoir for clean waste water.  Hope that helps.
