Getting ready for a fishing trip, have the trailer plugged into 50 amp service at my building. Turned on the furnace and frig to get everything set up and noticed that the furnace kicked off. It came on and was running hot air with plenty of propane. The frig lights were flickering set at auto. Switched over to gas and still flickering. Unhooked everything and plugged into 20 amp service with another GFI in line. Turned on the 12v lights in trailer and they flicker. When I put the 12v battery back in after having on a trickle charger this winter it checked a good 12.8 volts. The inverter also makes a low pulsing sound.
Don't know if you got my previous PM the other day so here it is.
Knowing your experience and knowledge base with RV's is way better than mine, I've got a question. Looking to get a new battery for the 2014 Sprinter as the original is getting weak. Any suggestions? I want to stay with a single unit due to space limitations.
