Quite probably because many of the usual suspects are over there elsewhere on the forums passionately arguing back and forth about hitches, tires and wheels, and big tow vehicles...sometimes it takes a while for them to notice a new post on a more useful subject.

Personally, since I'm a rabid 'do-it-yourself' type, I only have my long-standing AAA membership to fall back on in case of a serious breakdown. Most stuff I can fix myself with duct tape, or in a pinch, baling wire.
Since I drive a Toyota Tacoma and use Michelin tires, I rarely have the need for help with the tow vehicle...
