The reality is that what was once a well built toy hauler might not be today, some units are pushed out so fast that quality isn't job 1, its not even in the top 5. That said I hear pretty good consistent comments about the Northwood/Desert Fox, ATC, and Grand Design. There are some very high end custom units, but for most those are out of the price range. The Complete List of Toy Haulers (in the main Toy Hauler forum) lists those and many others.
Just as important though is a dealership. I've bought 3 from my local dealership, but before I bought one from them I spent a couple hours in the waiting room of the service center listening to people and hearing how they treated others. I talked to a lot of people to see if they stood behind their word or not.
Also you need to know about doing your own Pre-Delivery Inspection so you can inspect our new rig in detail. Also do not sign anything until after your PDI, once you do you own it. If you do your PDI before you can avoid problems before they start and the dealership is going to work to get things fixed faster.
Finally, don't rush. Spend time reading and once you narrow your list down check out dealerships and perhaps a factory tour.
