I took another look at my door setup, and, after reading TigerCub's identical thread, I've decided that a 32" door would fit. I only measured to the hinges before. But once I take all of the stuff off of the bi-fold, I should have 31 7/8"...enough for a standard 32" door. That means that I can get the Larson Secure Elegance as I mentioned, or I can get an Anderson 4000 series. They are basically the same thing. One big box store is quoting me $372 for the Larson and the other store is telling my $319 for the Anderson. I can get them in black with nickel hardware to match my bus too. It's a lot of money, but I think the final outcome will be worth it. I'll update with pics in my thread "later." Hopefully in about 3 weeks!
