Retractable Screen Door retrofit

We had Advanced RV in Ohio install a retractable screen in our 2012 Leisure Travel Free Spirit. It required adding in additional paneling and a plexiglass (?) piece on the countertop to hold screening in back of the counter. It works great, slides well but cost $$$$$! The only drawbacks are somewhat minor (besides the price tag)- it is now hard to close the curtain in back of the counter d/t the narrow space between the screen and the door.
We have friends who also have a Free Spirit with an Advanced RV screen door who recommended them to us. We're very happy with their work.
