On the bearings and axles issues, it is my experience that trailers are often neglected and abused. Home made ones are not always real straight and things are often not made true. All of those...

How do you regulate stupidity? Though they don't say it this way exactly, it is one of the biggest jobs of government. And, as pointed out, degrees of stupidity permeate the enforcement arena as...

Wow, there's a ton of knowledge and large pile of sarcasm in this thread. Even some BS. Makes it fun to read.

Well that's the rub with fuel economy. Add some nice aero like your shell, but it adds weight. Aero is king at speed, and the faster you go the bigger the difference it makes. Weight is king for...

Second trip. 166.2 miles. Without even looking at the fuel numbers, I could tell it made a difference. On trip #1 I had a hard time holding speed, and 80 mph was pushing it. With this (except...
