I don't frequent Ebay because I don't think it provides a good pulse of the GMC motorhome marketplace (love that phrase). But I have noticed that some here are turning up a few coaches for review here at gmcnet that don't pop up when I follow them to Ebay and put "gmc motorhome" in the search field. So, what phrases do you use that you find turns up miscategorized or otherwise harder-to-find GMCs?
update on phase 2:
Dave Silva asked me to preload all the boolean search parameters I could jam into to the craigslist gmc motorhome finder page in order to cull out as many of the Midas-type class b's and c's as possible for those using the page for their own DIY searches. Great idea! And it's done.

If you have room in the search phrase, you might exclude some of the more common GMC tow vehicles (to weed out the ones that include phrases like "this trailer towed like a dream behind my GMC Sierra").
Probably an easier one would be to exclude the common motor sizes like 350 or 454, though that could exclude an ad if the phone number happened to contain either number.

>exclude some of the more common GMC tow vehicles
I do that for my own spidering which feeds the GMC search page and it culls the false-positives pretty well. But as for the DIY finder page, I tested how much CL actually used and even though you can enter more terms, it ignores them after a limited number of characters.
Also, in related news, members here rightfully pointed out that there were some coaches missing in the earlier versions of the database. They were correct. In my past life, someone once asked what a site could do to discourage being scraped. My answer: rolling blackouts of sections of the website. After much research on other craigslist aggregators, I'm fairly certain that is what CL is doing now. This hits even Google, which -in turn- hits those that are using Google as their search front-end. I did a complete 'engine swap' for my site and the flood of new listings found is evident in the Most Current section.

The problem being, you want to find the idiots, but not waste too much
time. I've seen a fair number of coaches on CL that have 454 motors, but
I'm thinking (given the rest of the add), that they were wrong about what
they had.
It is a non trivial problem, it would be nice to find all the coaches
listed, correctly or not. Google Goggles perhaps (give it an image, it
finds what it is)? Or train our own neural network with the photos on the
photo site, and when it finds an add with matching images, it points it out
to us?
