Winnebago flirted with high-end coaches back in early 2000s with the Ultimate's - Ultimate Advantage and Ultimate Freedom, then they decided "that's not us" (a quote from one of their senior people to me years ago.) Then they brought out a blinged up Class A (42 or 45 foot, I forgot.) Their marketing director told me they didn't expect to sell a bunch of them (it's a completely different market) and certainly not every dealer would even want one on their lot.
Now I'm wondering if Winnebago tried to buy Tiffen, I think they are privately held.
