Old days
I had a 2002 lance 815 Took it up the Haul road (Dalton HWY) to Dead horse Alaska in 2007 owned the camper for 2 years. It held up very well. Did not care about the drain issue. MY only issue was that there was not enough leg room to sit on the toilet. Yes I am a tall and a Big guy. but even my small 5-2 petite DW found the Space in front of the toilet to be very confining. Other than that the camper was fine. MY only regret was the previous owner had installed a ESPAR diesel heater into the Stock heater system. I loved this heater very low amp drain and a wonderful dry warmth. I wish I had taken the heater with me before I sold It. Good Luck and Happy camping...
