Honestly, I live in Indiana, and I can't remember the last time I saw a Toyota with any rust on it regardless of which vehicle platform you're talking about. Same for Honda's. I know when I was in high school (early 90s) the old Toyota trucks had a terrible rust problem, but anything built after 1990 seems to be impervious to rust, at least around here. I'm in central Indiana, and if you find a ford, Chevy, or Chrysler that's over 15 years old without any rust on it, its either from out of state or its spent most of its life in a garage. Its hard to find a truck over 15 years old that isn't completely rusted out. I'm pretty sure that Ford sprays their trucks down with saltwater and vinegar before they paint them just out of tradition......
Well I am recalling back when I ran a welding business
and I've welded everything from HEavy Equip Dozers etc down to .050 SS

One time I even reworked the whole front end of a Delorean that was made up to look like the back to the future car
Most of it was made out of 16 Ga (Thin, bent etc)

About 2008 a guy asks me if I can weld on his Toyota Fender because it was coming apart
I am used to older 70's Fords, I drive a '92 Dodge, so I said sure.
You can actually screw in a sheet metal screw into their steel and have it hold a mirror back on

That Toyota Tacoma fender was so thin from the factory I kept burning through even with tiny tack welds
I had to butter each side up with weld, then stitch each side back together very slowly
---
by comparison I had a '63 Ranchero that I poked a hole in the front fender at work by accident
took the fender off, pounded the steel back into shape, and zipped it up with a MIG
No issues and didnt have to baby it while welding.

There was no way doing that to the newer Toyota, it was like you could almost dent it with thumb pressure and lean on it.
But yeah I get it, they want them lighter plus going to half the thickness of metal also saves money right?

Another comparison to that
I was doing some backhoe work in the backyard and had the backhoe extended and didnt look and was backing up and the tractor stopped
I had hit my '75 Scout in the front end just above the grill
it barely dented the hood and completely stopped the tractor in low gear.

Just my experience
I'll keep the Old 70's -'90's trucks myself
