I can't take the thought of any more chipping of the thin paint on my 3rd Gen which is already pretty sad given that I only have 4300 miles, so I decided to put use 20 square feet of 1/8" HDPE that I had laying around the house. Total budget was probably $180-200ish if I was to purchase all the pieces at once.
Materials:
-Front mudflaps: two pieces of 12x27" HDPE, 1/8" thick
-Rear mudflaps: two pieces of 12x26" HDPE, 1/8" thick
-Rear 1/2 fender liners: two pieces of 12x32", 1/8" thick
-A bunch of M6x20mm and M6x25mm bolts with nuts... I lost count. Stainless recommended.
-A bunch of M6 or 1/4" stainless washers
-1/2" wide x 1/8" thick aluminum bar to make rear mudflap and fender liner brackets.
-A beer or two and a whole weekend.

I won't type much as the photos tell most of the story, but feel free to ask questions. There are many possible configurations for the mudflaps and fender liners and I went for maximal coverage, but you can certainly go more minimalistic. The rear 1/2 fender liners were definitely the biggest pain in the arse, but I'm happy with the finished product.

Doing full fender liners seemed like overkill given that the back half of the wheel well is enclosed. I used a cardboard template to fashion a front half fender liner to stop rocks from being thrown forwards into the fender. This should reduce gravel noise and prevent rust spots from forming at rock chips inside the fenders. I also opted for hybrid inner/outer fender liner design to provide coverage for the lower fender lip and outside of the fender where rocks are thrown forwards. This worked out nicely.

GN,
Wish you would have asked first!!!!
If you want to buy all the flaps that come with a '22 SV LWB I'll sell you mine (make me an offer + postage). I can't stand the dam things and removed them when I got home from the dealer (TN).
**Note: you have to have all the screws and push tabs (I put all those in the holes so it doesn't look like anything is missing)

Errrr

?! I'm really confused as to why you might think I'm looking for small OEM mudflaps when I built a giant set of custom flaps. I'm not your target customer. Plus I also have a set to sell

Reminds me of the rokblokz I had on my Tacoma. Good job. Probably was way more cost effective too.

I wish that company would get on board with a set for our 3rd gens? Seems there is a demand to swap out the oem … 🤔🤷‍♂️

Just checked the website and these are not made for the 3gen

But that doesn't mean it won't fit without maybe doing a mod or two?
@The other Sean, how does this flap mount to the truck and how many anchoring points are there for your specific ride? Curious to see if these would still work?

I took the OEM flaps, laid them on top of the Husky liners and marked the holes to drill. I used the OEM screws and screw holes in the fender. At the very top I added one self tapping screw but you could cut some off. I left them full length because I'm Titan swapped.

Yeah, I realized what you were referring to as I was googling all these mud flaps this morning. I may get a set for the front and literally just put them over the OEM so the inside of the wheel well covers the oem ones, but on the outside you just see the Long Johns extend past the oem flaps?? I'll have to see about the room available and thickness with the screws in the fender. Appreciate the link to them as well

You won't have room for both. You get more room than the OEM flaps.

Yeah, I saw these and thought they were WAY too much for some mud flaps IMO. I'm sure they are sturdy, but maybe a bit too much material/engineering for what I was looking to do? My truck is not lifted, so the longer flaps need to be a bit thinner/softer towards the bottom should I hit something. I do like the Husky Long Johns a bit better for easy of placement and thinner material. I'll have to see
