Yesterday's trip:
Yesterday was a cooler day, around 7-11 Celsius varying throughout the day, with some light rain.
Overall load wasn't too big either, around 60lbs of tools for the trip there, and I'd say an extra 300-350lbs from picking up seats, brake discs, and other misc parts from the junkyard, and other shopping.
In total we drove 431.4 KMs, with around 100 KMs of mixed stop and go/urban highway driving and the rest all being highway, average speed for highway sections was just under 100 KpH.
Despite all of the urban driving, idling in drive thrus, accelerating from stop lights only to drive a few hundred meters to stop, and accelerate again. We achieved a surprising 10.63L/100Km or 22.12 MPG.

On our last trip, which was done before the tune up, ignition upgrades, minor weight reduction, and summer tires we achieved 10.52L/100KM, which is around 22.40 MpG over 640KMs of strictly highway driving.
Yesterday's trip involved more weight in payload for both legs, and quite a bit of stop and go traffic as I navigated busy downtown roads to visit different stores and appointments. Yet we achieved almost exactly the same mileage! I'd call that a win for sure.

Other observations:
With new seats I'm desperately hoping I can clear the last of the airbag codes, the last few that came up referred to seat belt pretensioners, which on these new seats are thankfully not deployed.

Other observations:
- Acceleration has improved from the new ignition, it's hard to say how much but response is clearly better and as a result it's much easier to pass vehicles on the highway. The engine note is certainly more aggressive
- We encountered at least one misfire, one code reading specifically for cylinder 2 whether it's from the new wires, the coil, or the gapped plugs I can't be sure. I need to do a better job of routing and securing the spark wires to make sure they don't move as much while in motion. I cleared the code and drove another 240KMs without issue.
- A low vibration at idle is still present, and in fact maybe more noticeable following the ignition upgrades. It may be worth running compression tests to make sure everything is healthy.
- Firestone Destination LE3s performed excellent on the highway in rain even at speeds exceeding 100 KpH, I didn't notice a moment of hydroplanning and felt confident the truck was tracking true.
