A standard 18" extension that goes into a factory receiver is rated for 350/3500 as long as the factory receiver is rated for it minus 1/3. My stock receiver is rated for 600/6000 so that puts it at 400/4000 with the extension. Both my boat with trailer and my wells cargo are much less than that so I would be good with just the extension. Even though I would be fine I wanted a little more for our rough Alaska roads and here is what I came up with using stuff I had laying around.
A while back in this thread I asked about the rating of the factory bumper and found out it was rated at 500/5000 so I decided to go ahead with my extension plan.
Here is a picture of the plan from the bumper thread:
.
With this design the tongue weight of the trailer will be transferred into a straight pull on the factory bumper which has a pull rating of 5000 pounds. The upper link is a upper link off a tractor three point hitch so it is stout. The upper link will also add a quite a bit of straight pull support.
Here is the project about completed. I still need to weld it all up and then paint it.
.
Here is the view from the back with step up and down. Notice it doubles as a license plate holder as well as a electrical plug mount.
.
This triangulation of the extension makes it solid as a rock. Any constructive criticism before I weld it up and paint it???
Don't comment on the fact that I can't get the pin out of the rear end of the upper link due to the electrical plug in the way. It was designed like that to keep the pin in even if the clip falls off Or I might run the pin in the other way after I remove the plug to paint it.
