Have a 2016 Bighorn 3270RS with Frigidaire refer; onlycamped twice with this unit. On the secondtrip (while on shore power - only a overnighter) during the night the refer tripped.Reset the Inverter switch in the cabinet unit came back on however, after waking a second and third time foundthe unit off and reset switch each time (an hour or two in-between). Found referoff again in morning reset again and refer ran fine till left campground. In AMwent outside and opened door to where the inverter is located and the Inverterwas making a funny sound (ping) about every 5 seconds or so, also the voltageindicator was going from approx. 11.5 to .005. Anyone experience this problem?
