I enjoyed Andy's article, but one thing that really confused me about the concept of having an angled ball mount...or at least, the manner in which it was presented, is that this is somehow..."news".
like...people don't know about this??
Its in the instructions from your hitch manufacturer. RTFM, as we say in the computer biz.
But apparently, its true. people don't know about this. So kudos to Andy for pointing it out. but if you read your hitch manufacturers instructions, you'll find them to be in alignment (pun intended) w/ Andy's advice.
