Jim:
I home-made a front "bra" to protect the aluminum skin by using black rubber carpet runner from Lowes. It was 3.00/ft. Attached it under the roof/wall trim on the sides, used stainless steel screwes along the top edge
and used the small black license plate caps to cover the screws.
You can look in my gallery fo a photo. It has worked out real well and was less then $18.00 to make.
