Over the weekend I noticed a few rust flakes on the ground near the back of my 05 Excursion. I looked around under the truck and the bottom of the hitch (receiver) was showing moderate rust in several places. So was the skid plate on the bottom of the fuel tank. When I bought the truck used it already had 90K on the clock and was from PA, and very clean. I inspected the truck and the hitch didn't look very bad. In about a year since we got the truck the hitch I'd say is showing more aggressive rust.
My question is this:
Should I remove the hitch and sandblast it, then repaint and reinstall it?
Should I use this as a good excuse to replace it with something better? If so who makes an upgraded receiver for this truck?
We are going to be towing around 10K to 11K with our truck and I'd hate to have a failure on this part.
