I happened upon an ad for the Tow-Buddy device in Trailer Life and visited their website (www.hitch-buddy.com)
. What an interesting device. It is rather pricey at $6500 but it supposedly works with fivers, goosenecks, and trailers. It has an integral reciever hitch that allows you to hook up your trailer (and I assume the weight distributing bars). The manufacturer indicates that it removes the trailer weight from the tow vehicle. Supposedly it is NHTSA, SAE, and DOT certified. Looks like it would add 4 feet or so to your trailer length.
I thought that some on this forum would find it interesting. Anyone used one for any vehicle or for a trailer specficially?
