I've just spent the last three days at the Minnesota Inventors Congress. One of the inventions on display was very interesting.

for the Hitch Helper. It won an award and looks like a very good idea for trailers.
It won't work for long overhangs like on motorhomes as it does not castor.
The folks behind it are very nice and seem to have a super attitude. Other than meeting them there I do not have any other experience or connection to them.
