rick, i find your method interesting. i usually close the rear section, then put a medium sized metal ladder on one side near the debris, sweep it, then move to the other side and sweep again. guess i'm "AR", but i then got inside the front section, which had not been closed yet(we have a slide model) and cleaned the dirt off the front edge of the rear section
. dirt and pine cones and leaves had accumulated for about 4 years when we bought the unit from an elderly gentleman this year. thanks--i'll try your method to see if it's easier! 2swans
