About the only time i see any of these is if there is absolutely nothing else on that I am interested in, or it is one as I search the guide for something to watch. One has someone looking to upgrade. Well it seems they bought a unit in their budget but there was no mention on the $50,000+ truck they will need to pull it.
There is one where they rebuild classic trailers that isn't too bad. The ones with the high dollar rigs do not interest us at all as our needs or wants are much less. We are happy with our 30' fiver and camping at National parks, Forest Service areas, State parks and the like.
Someone must be watching them because they are still one and renewed year after year.

You can't make things idiot proof, you can only make them idiot resistant.
