CO detector--thanks November 06, 2010, 12:40:12 am Yahoo Message Number: 118042Hi Thanks to all those who responded to my question.I went to Camping World today to check out what they had. Two different brands other than Costar at around $70. But they had a diffferent footprint, and were 12V ones. I think hard wired detectors are the trend now. I wanted a battery powered one.So I ordered a Costar 9RV online from one of the places recommended by one of you. Thanks.Tom Johnston, Whidbey Island WA, rain but fairly warm
