"Tino" 2023 Tundra SR5 CrewMax TRD

WildernessRimFab · Jun 5, 2023

This is my fifth Yota truck now, he is joining is siblings a 1996 T100 and a 1972 FJ40.
The new Tundra will stay relatively stock for a while, but Im going to start a thread since there isnt much info on 3rd gen Tundras on IH8Mud.
Long story short, I ordered a similar truck in October 2022, got sick of waiting in May and found a truck in transit to a nearby dealer.
Picked it up on May 19 and got the AT Atlas topper installed the following day.

A couple simple mods since then:

Installed Firestone 4614 Airbags in the rear coils (These are for a 200 series LC but they fit)
Some folks claim to install these without removing the rear suspension, I didnt want to knick my new coils with a saw so I removed the coils.
This was pretty simple, I removed the swaybar and top shock mount, as well as the bracketry for the brake lines and rear axle wiring (ABS/E-Locker).
Cutting the bumpstops was nasty, I used a sawzall and it made lots of smoke.

Installed one size up tires: Falken WildPeak AT3W 275/70R18.
The spare barely fits (fully inflated), but it fits.

Thats it for now, I plan on bulding a bed storage drawer in the bed and adding a bumper over the Summer.

I fabbed up an aluminum wind fairing frame in an attempt to reduce wind noise and gain back some lost mpgs from the camper top. This was my first alu welding project with a spoolgun and it kicked my butt for a while until i got my settings dialed. The entire assembly attaches to the camper using pre-existing captured fasteners. I scored a large scrap of 1/4 inch thick ABS from a friend who works at a plastics manufacturer. I dont know how much of a difference it will make but it certainly wont make it any worse.

Looks good! How are you liking the Atlas so far? Did it come with the window or did you add that?

The Atlas is awesome. Its super quick to deploy and secure. About 2 mins transition time on either end.
I ordered it with a front bed slider window, passenger side slider, and rear hatch fixed window.
It would be a nervous operation adding large holes to the Atlas, it wasn't cheap and I hope to get 15+ years out of it.

I've had the truck since May and I probably have ~20 nights in the Atlas so far?
Some nights solo, some nights with one kid, and some nights with wife and both kids.
4 people is ok for quick camps on road trips, but 1 or 2 people is pretty luxurious.

Happy to report that I drove about 6 hrs total on the highway and paved rural roads last weekend and there was a gas mileage improvement of 1-2 mpg with the fairing that I made for the Atlas topper. Cruise control at 70 mph on the highway and 45-55 on back roads netted a total milage of 18.4 mpg using the dash readout with a 3% correction for the larger tires. 18.4 mpg isnt near the posted EPA numbers of course, but this isnt too bad considering oversized 10-ply AT tires and the Atlas camper top.

Dead thread resurrection...installed a couple electrical items recently that I am happy with:
1. Engine Start/Stop Delete unit from Amazon - this starts the truck with auto start stop turned off, you can still turn it back on with the button if you want.
2. Experimental Designs Freedom Locker - This is a piggyback wiring harness that lets you activate the rear diff lock in 2H, 4H, and 4L. It uses the factory diff lock button. The dash locker light doesnt illumate, the freedom locker comes with a small blue LED that you use instead. I installed it next to the parking brake button. Seems to work great.

Starting the install on the Ironman 4x4 Apex Triple Hoop Front front bumper. I bought this several months ago but the winch was on backorder.
Unpacking the thing took over an hour. Ironman did a great job (too great?) with padding, tape, and cardboard.

Finished the install, 3 evenings solo after work then a full day with a buddy helping out. The instructions are non-existent minus a youtube video, I figured it all out but would have been faster with less guesswork on which hardware to use in a specific location. Installing the winch control box required some thought, I ended up severely modifying the ironman bracket and relocating the passenger side horn. All in all, it fits great and looks great. I wired up both sets of lights (driving/fog) to the OEM fog switch on the turn signal stalk.
