Black adjustable rear ladder

I want to install a black rear ladder on our new TT. I contacted Keystone and they told me it was braced at the bottom and top of wall for a ladder. Problem is they don't sell one for the Outback TT since it is not a factory option or standard feature. Therefore, I am stuck trying to find one that I can adjust the support legs so it hits the bracing. Even harder is finding one in black. Any help greatly appreciated. Tks
