I was looking for a replacement inner dome for my 14 x 22 shower skylight in my motorhome. I was getting discouraged as the prices on the internet and large dealerships were what I considered outrageous. Then I ran across Byerly's listing for this inner dome online. I took a chance and ordered it and am very happy. It fits perfectly, the price was outstanding, and the shipping was reasonable and fast. Thanks, Byerly RV. When I need any other replacement parts I'll be checking your website.
