I have a ladder I purchased to make getting up in the top
bunk easier. It is the same one sold here:
http://www.van-cafe.com/home/van/page_536_566/folding_westfalia_bunk_ladder.html
It retailed for 150.00 when available. It's light and folds for
easy storage. Made getting up top easy. With the recent 
right knee issues and the previous left knee  replacement 
I am just sleeping down below now. It's in great shape I just 
see no need to keep it. $70.00 plus shipping from 06355
