Customization Help

I have a delima. I'm 6' 8" tall and not on the slender side either. I own a 1999 HD Ultra Classic Electra Glide. I am in the market for a new bike. I didn't fit very well on the Ultra Glide, always hanging my legs over the row bar on long trips. The brake and shift controls were always too close also. I really like the looks of the Road King Classic, but the dimensions are very similar to the Ultra Classic. Do I find someone to build me a custom or does HD have a longer framed bike? I have heard custom bikes are very expensive.
