This is a simple principle that you won't see when crunching numbers before a purchase. But you'll see it when your knock-off ride breaks before its first oil change. Buying quality name brands buys you reliability, in most cases. Breaking down on a ranch, or a long way from your truck, or just about anywhere is not going to make you happy. The knock-offs use cheaper materials that are often not even tested for durability, so you put not only your adventure in jeopardy, but also even your safety.
