We got our Frontier Scout in June this year and have been very pleased with it.
I have only looked at the new Autotrail range on the internet but they do look as if they have made on or two changes to them such as rounding off the corners in the kitchen and changing the upholstery.
We are calling into Brownhills tomorrow on our way to Rutland so,hopefully,we can have a nosy at some of the new models!
To sum up I think the quality of Autotrail is very good and I would certainly buy another (although it will not be tomorrow!).
