We are at my daughter's house in South Jordan, Utah for about a week, then we will go to our daughter's house in the Phoenix area for a few days. I checked with Camping World, and was told a fender could be ordered from the factory. We all know what that would mean. I have one back home, but that is in North Carolina. It is one that was not quite right which is why it is at home.

Does anyone know of a place in the Salt Lake City area or the Phoenix area where I might be able to find a fender? I would like to have one in place before we leave to head back home.

Edit:  Also, what is the best way to patch/fill the old screw holes? I'm pretty sure a new fender's holes would likely not line up with the existing holes.

I would make an epoxy/wood fiber filler that you can pack into the hole. Find an epoxy that is fairly liquid, and mix it with a small batch of wood fiber (AKA saw dust) until it is about the consistency of peanut butter. You just don't want it to run. Then poke it into the holes with anything small that can get into the hole. Once you have it full, tape over it with masking tape or duct tape or whatever tape you have laying around. nce it's cured, you can remove the tape and drill it to accept screws.

When it happened to me I had to order the fender from the factory and the factory had to ship it to an R-Pod dealer.  I don't know, maybe they could have done Camping World.  I guess the point is, you probably aren't going to find one locally.

I don't remember: are the right and left fenders the same?

I almost want to use one of the diamond plate ones that is squared off to have a flat top to use. I'll be weighing options as we travel and likely, not do anything about it until we get home.

That's what we did.  We drove home with "one shoe off, one shoe on" and ordered a pair of the flat-top fenders.  We were able to salvage the marker lights off the mangled fender.  Required some splicing of wires that were ripped off in the blast.

They are aluminum.  We were headed out on a trip, so I Plastidipped them with a few coats after scuffing them up.

No good.  The Plastidip adhered to the aluminum, but rocks chipped the heck out of them.  I'd said they're 50% Plastidip and 50% bare aluminum now.  It's ugly (or rugged, depending on your perspective), but I haven't been motivated to actually paint them.

I did find one more item that was damaged. The cover for the black water tank flush port was ripped off also. I'll need to find a replacement cover. I may need to replace the whole port. There are some scrapes on the side from the screws when they pulled out. It looks like the tread hit it and it started separating on the back side and then peeled off toward the front. The fenders sure are not sturdy enough to take the impact of the tread. 

The worst thing was that these were Carlisle load range D tires. There was wear and I was going to check them when I got here to our daughter's house. We did not quite make it. We now have new Goodyear Endurance load range D tires. Hopefully, they will be good for a few years.

Powder coating would be pretty robust.  I'm not sure the truck bed coating would stand up to the abuse.  But let us know if you go that route!

EDIT: I called the local Line-X franchise to see what they wanted to do my running boards, and the guy on the phone quoted me $675. I guess he didn't want to do it.
