Are there any mfrs with bad overall reputations?

I'll bite, since you asked. If you were a friend or a family member and you asked the same question, I would honestly tell you I would not buy myself another Forest River product, a Keystone product, or a Fleetwood product. While there are many that really love these brands, "I" have been disappointed with their quality.

That doesn't mean that there isn't happy owners, I just answer what I'd do if it were me.
