Since all the appliances are generally the same, it's the construction of the box and the frame/suspension components that actually set the better trailers apart. It's like pulling teeth sometimes to get info as to how these units are built. Solid surface counter tops do not a quality trailer make. What's the floor made of under that linoleum? What type of glue do they laminate the sides with? How much time do they take in welding up the aluminum side frames? (not much from the videos I've seen)
Unfortunately, taking a factory tour is not a walk in the park if you live hundreds of miles away. So far, I'm having to go on reputation. The trailers I'm looking at seem well made but even the higher price stuff apparently occasionally comes lemon scented...
But then again, when reading a rant you don't know if the person posting has genuine problems or are just impossible to please. I know a guy that is that way. Instead of adjusting something, or adding a screw, or touching something up, he raises hell about it and then doesn't understand why he never has his trailer... and why the dealer is charging him out the wazoooo for every little thing since the warranty expired.
But I have until early spring to make up my mind... I'm looking at Grand Design, Jayco Eagle, and Winnebago Ultra Lite trailers. Open Range was on my list but I could never find a floor plan that really fit. The Winnebago has been the hardest to get a good feel for, because like Grand Design, the TT part hasn't been around long. It seems, however, that the dealers around here can't keep the Winnebagos in stock. That's actually my front runner right now. The GD Reflection and Eagle are tied for a close second. But the Reflection doesn't have a floor plan I really like, nor does the Eagle. It may come down to availability and what kind of deal I can get.
