"Any ideas on keeping a RTT cool at night when parked at a conventional campground with full hook-ups? The campgrounds in question only has full hook up sites, so why not take advantage of it. "

"Tried the Zero-Breeze yesterday. It was 84*F out and that thing blew nice cold air! Should have put a thermometer into the duct to see what the temp actually was (next time), I will say that it was at least equivalent to two dash ducts on max A/C. Ran nice and quiet. So far I am impressed.
The big test won't come until June in Florida."

"The ZERO BREEZE Mark 2 works great! Last week in Orlando mid 90's during the day and 76 at night. I set the a/c unit on a sheet of rubber on the roof of the truck, ducted the outlet into the top of our king-sized RTT with 12x12 annex. The rtt was cool and it took the humidity out of the annex and dropped it a few degrees. I had it on high for about a half hour then to low over night (off during the day). That was with it plugged into an outlet, they say it will run for 5/6 hours on the battery which is an upgrade.

To make it more efficient, I should have placed the unit inside so that it was recirculating the air instead of trying to cool the outside air. Then you duct the intake/exhaust outside. All of the adapters are included.
Net result, yes it made a huge difference, yes it was worth the cost ($1400 with one battery). I cannot say that it will make it like an ice box but just taking the humidity out, and circulating the air is huge. Also 10 degrees difference is noticeable! I am sure that if it were only trying to cool one unit instead of tent and annex, it would be even better."
