The manufacturer of the retrofit ladder has indicated that he is interested in marketing the ladder if there is enough interest. He has installed one prototype and it has, to his knowledge, performed well. If you are interested please contact Hanz Ruiz at (310) 516-9812. The price sounded reasonable to me. Please e-mail me, also, if interested at jamay@thehaskellco.com Thanx Jerry & Cheryl May aboard Fantasea
