Interesting question.



Let me think....
~Plan "A" What about having someone screw in a small bracket on the inside outer section of the bunk. Attach a strong cord to the bracket, maybe put a handle on the end of the cord. So when opening the bunk up, you unlatch it on the outside. (The bunk will stay up as mine will) then go inside and grab the cord and or handle, give the bunk and mattress a little push and hold onto the cord to ease it down. On closing it back up, on the outside, un zelcro the material, fold it up (the tenting material), go inside and pull the cord. After using the cord just tuck it under the mattress.
~Plan "B"Get a old broomstick with a 90 degree hook on the end. Un latch the bunk, hold the hooked broomstick on the upper lip of the bunk and pull it open a hair, then use the broomstick to help ease it down.
~Plan "C" Ask for help....when you arrive at the campground. From 25 years of camping, I have learned fellow camps are there to help....
