Northern Lite truck to camper cord

My leg was not long enough to push brake pedal while truck is in reverse and then look at the lights at the same time. one other problem`the week before I bought the camper it had not rained at the dealership and it has not rained on the way home and still has not rained. before we left the sales lot the dealer had the camper washed they put the camper on the truck. When I got home I was going to take the camper off the truck, the remote did not work the dealer had me try and jump the circuit breaker, that did not work. called Lippert, HappiJac they had me check the board no light that should have been on but there was water in the enclosed area where the holding tanks and the circuit board is located. I do not know how water got in that compartment maybe when it was being washed the door was not latched but apparently the water shorted out the board. HappiJac was happy to send me a new board I paid the shipping. A drawer the dealer was suppose to fix because it would not stay shut when the truck moved with the camper on it, I fixed the drawer at home, when we inspected the camper the carpet was rolled up after we had them roll up the carpet because I have a basset hound there was a scratch in the vinyl just saw the carpet was rolled up I did not enter the camper again until I was about 200 miles away from the dealer. I started the generator the propane smell was almost like unburnt propane, the one propane tank went empty in twenty minutes. After I parked the camper on the way home I moved the curtain by the window that is right behind the rear window on the truck what I saw was a stream of dried glue about 4 or 5 inches long. yes there were a couple other small problems which are my problems now. The new dealership in Jacksonville Fl does not yet have repair men on site the dealer (owner) told me that The dealer is sending me a ambilical cord 20 foot long, because the factory installed 7 pin connecter checked out perfectly on the truck, the one in the front left side of the bed does not have a good ground. I hand cranked the camper off the truck at home after I got home ,remember bad board,(98 degrees that day) I needed the truck. So when the cord arrives the truck pins are correct so if there is a problem we then know it is in the camper. Thank all of you who were objective and for those who were sarcastic Thank you for your sarcasm and no help
