We just finished a great weekend of camping and while we were disconnecting from the 30 amp power source we discovered the plug to be extremely hot. After further investigation we noticed one prong on the male plug was very hot, it was discolored with both a copper tone and black soot, in addition the black rubber insulation around the prong had started to melt due to the high temperature and assumed arching. This was the 8th time this year we camped at the very same lot number plugged into the same power box and never had a problem before. Now the real question is do I have a problem on the RV side or is the campground connector bad? Also, at the time we had both the AC and the hot water heater on, which isn't different from any other time in past, maybe we shouldn't run both at the same time. Anyone have any thoughts on the possible cause? And, most importantly, do I now need to replace the power cord to the RV?
We have a 2011 Crossroads Slingshot 21FD. Any help would be appreciated.
