Re: Explorer Bumper Hitch - Should I use this or add a frame hitch?
If you think that the steel of that bumper and a receiver hitch steel are the same you are severely mistaken. First the bumper steel is about half as thick. As far as the mounts, you are wrong Again. The bumper brackets mount to the side of the frame rail with two bolts each that are anout 1.5 inches apart, and then stick out about 4-6 inches. You understand that it makes the bumper a big lever? A receiver hitch bolts to the bottom flange of the frame with two to 3 bolts and they are spaced at least a total of 3 inches apart (more like a foot on some vehicles). No lever action there.
I'm completely aware of the fact that they are not the same. Its all about what a particular setup is designed to withstand - ie: load. Lighter loads place less force/stress on a componet so the fact that it may be of a lighter gauge and mounted differently is of no practical consequence. You might also consider that, by your argument, everyone who buys a receiver type hitch should purchase a Class V unit even though they may only tow a 1,700 pound boat/trailer. Obviously they wouldn't for a host of reasons, starting with the fact that a Class V won't fit on most vehicles, but hopefully you get my point.
Stay within the limits of what you are using, maintain it and drive sensibly and you should be fine.
PS: Gary, just a word on chains ... I know this seems like blasphemy but if you might want to consider chains that will break. I once had a 5,000 trailer come off of a 24' U-Haul truck. U-Haul had told me that the ball hitch was welded onto the, dare I say it,
bumper hitch, so I never checked the nut/cotter key it over the course of a 3,000 mile move. As it turned out, the ball wasn't welded and there was no cotter key to prevent the nut from backing off - which is exactly what it did 100 miles from my destination. I hit a bump and the ball jumped up, and out of the bumper. During the 60 seconds or so that it took for the chains to break, I truly thought that 5,000 pound trailer was going to flip the 20,000 pound truck I was driving. It was jerking the rear end of it around like it was a Toyota. I know the law says we have to use safety chains and I have them on my rig, but after that experience, I sometimes wish they weren't required. One thing that I should mention as a mitigating circumstance though, is that U-Haul trailers with surge brakes have a third chain that yanks something in the system which set the brakes as the truck and trailer separate.
BTW, I have a sister who lives in Cornelius - you have some great lakes in your neck of the woods!
