We've used them as a resource in the past, and would do so again in the future.
They (used to?) sell a book on teaching how to inspect an RV yourself, how to look for important things and look past colors, fabrics, etc.
There are lots of interesting "rumors" past around about them. Like how they don't actually inspect RVs (they do), how some makers pay them for good reviews, etc.
I suspect many of these are started by dealers and builders that don't want the buyers to have as many tools available as possible.
At one point the principals were "banned" from attending local RV shows, a move by a few builders (now gone) and dealers (dito).

When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.
