Wow... you guys are like mechanical engineers... .. all this information is very helpful.. I did pull out the owners manual last night and read that the battery will not over charge.... and yes... I did pull the plug... then tried lights in the RV.. none would work... hit the switch at the door.. and the lights worked.. hit the switch again.. no lights..then plugged it in...
Gene in NE... interesting .. I had seen these little levels in the RV section of Walmart... so I picked up a package.. and now I know what to do with them.. thanks...
also.. my RV has a leveler ... it's manual... there's a long rod.. like the one used to operate a car jack... and I see where that's used in the front of the RV.. the previous owner pointed it out to me.. but no demo... I did not try to use it...for fear of messing something up... wanted to wait till I get to my friends RV Park .. no doubt Mr. Wonderful can show me how to use it...
Thanks for all your comments... I know just where to come to now when I have a RV issue...
