Thanks for the reply, Yes I am going to take out the existing 40 amp converter. It may be defective because it runs 24/7 even with the refer and everything else shut down. There are no batteries on the Trailer now but I am restoring a couple of deep cycle 6 volts left over when we changed our off grid battery recently. I will install those at some point. No need as of now. I am going to research converters to see if the newer ones have better power use, it does not seem the converter should be drawing power when nothing is in use. I like the idea of running 12 Volt to the trailer but I just covered the darn ditch, arggh.
Thanks for the mention of Sun Electric, prices are good. I have gotten most of my equipment from Northern Arizona Wind/Sun because they are in my area.
