Welcome to the forum and congrats on your decision to get a motorhome.
I'm not super experienced, but I'd say Winnebago is a good choice. They've withstood the test of time for many years and they're still around. That's gotta say something for the way they do business.
As far as Chevrolet or Ford. Tough choice there. When we were in the market, we also considered a class C. One of my clients is a 3rd party company that does maintenance on one of our cities bus lines and they run the buses that resemble class C's. A couple of years ago they were in a transition of phasing out their Fords for Chevrolet's. Probably a bid process. I spoke to a couple of the mechanics and they said they'd choose Chevrolet over Ford. That could have been a case of the Fords being older and the Chevy's being newer and less prone to age related repairs.
Me personally. I'd choose a Chevy with a big 8.1 V8 over a Ford with a V10.
