Evening ladies and Gents... I'm trying to cool a 26' Pace Arrow (1980 Vintage) in Texas's July and August high temps with a 4k gen set. The Carrier Air V 15k BTU A/C is rumored to cool like a 17k BTU unit...any first hand information on this a/c ?? The 4k gen set is a strong low hour unit in top shape (as is the coach believe it or not)..but so far one ac has not been even close to adequate when temps are over 100 degrees. My customer has a new 7k Mach 1 Coleman that I could install with the 13.5 Duo-Therm already on the coach...(I know, too much for the generator..well not really with a sequincer..but VERY close to overloading). So close that even extreme head pressures on super hot days might put it over the mark...hence the Carrier approach. I am a general repair shop...and sure could use some first hand information from anyone who has dealt with this problem successfully and/or anyone who has tried the Carrier AirV 15k BTU ac..... Thanks......... Stan M.
