Similar situation while in Denver area with propane to refer, just too low to keep food while boondocking..on 120/12v worked fine. Stopped by Ketelsen...they were very busy got me in about 40 mins later...checked the pressure on the regulator way down...cleaned and adjusted...made sure hoses were fine...called me into the garage to check everything before they backed her out...I asked a question to the two guys about the my battery separator being very very hot...they looked and said you got some tools I told them yes...then go to parts and get a new separator...I did and when I came back out and paid my bill to service, I went to change the separator I found on the step a few wire connectors and two 12" bits of wire with the ends trimmed waiting for me. Did it in the parking lot...as a came out of the TC the two guys were at the other end of their big building looking my way...they held their thumbs up and so did I...one yelled out "you all set"...sure was...yelled a big THX back. Good folks there too...a bit pricey but when you are used to doing everything yourself paying for something seems to stick in the craw no matter the cost...but well worth the stop and the layout.
