The Bible says the fear of the Lord is the beginning of wisdom. The beginning of wisdom for towing, as I see, is going by the published standards for a truck, tires, frame, hitch, controller, and, like Dirty Harry said, a man has to realize his own limits. Then consider how fast you want to go, the terrain you want to travel, your experience in the worst case scenario for your drive, and, most of all, can you stop your rig. I think every "newbie" should take the time to read that "forever running" post on here about the Ford/5th wheel crash in the mountains, not for any reason other than to put a little healthy fear in your bones of what it is we do when we get out of the safety zone with our equipment and with our mind and experience. There are some posters on here that I would get in a 20% overloaded rig with them, go thru unfamliar mountain roads at night, and catch a nap. There are some on here I wouldn't want to ride with in the daytime pulling a lawn mower trailer in familiar flat land. You , me, all of us, need a fear of the Lord, and a healthy dose of understanding of what it is you want to do towing. Take the maximum limits and subtract for terrain, no exhaust brake, no maxbrake, no free spin if you have a 48re, no real world experience. Don't even think about hooking to anything with Chinese tires on it. Learn from others' mistakes, and our (your) own. When we get skid marks in our drawers, and live to tell about, learn from it! My sermon for today. Mark
