Is the Lightning frame and underbody more corrosion protected than a regular F150?
From the looks of the undercarriage in that video the OP posted, I'd say less protected than a regular F-150 because there appear to be more nooks and crannies around the battery box where road salt could hide.

He was reviewing the '25 Flash that has been dumbed down a bit from '24. My '25 is missing the power tailgate, spare tire, tailgate step, desk, rear light bar and still AA trip planning. It has the 123 KWH battery as well. Some of those things are options.

The one thing I most agree with is the shifter. It feels cheap and prone to fail. It's only a switch. I really like the rotary mod but not enough to do it.

I was also a bit surprised by his recommendation to buy F150 but stick with ICE.

No more than a regular F 150 and only a concern if you live where they salt the roads AND one doesn't utilize proper maintenance like under carriage washes.

Laziness is essentially the cause of automotive cancer.

Actually, if you watch those videos I referenced earlier in this thread you'll see that the cause of cancer on the F-150 is due to Ford not coating the frame properly and not installing covers over the holes that are all over the frame like swiss cheese. Ford welds the frame along the bottom so that water can't escape easily, but then has lots of holes in the sidewalls of the frame with no tape or protection over them. It's a recipe for disaster. Other automakers don't do this.

It's still a matter of an owner being lazy and not properly washing the under carriage where they salt the roads.

We don't do that where I live so it's ok for me to be lazy about it.

Amen. My lazy-man's carwash does the undercarriage as a matter of course, but we're washing off red mud in GA...not SALT!

I think you're still missing the point. There are holes all over the side of the frame. There are not holes all over the bottom of the frame. Therefore EVEN IF WASHED REGULARLY the road salt is going to sit inside the frame moreso than it should.

Did you even watch the video? The inside of that frame was full of junk, and by looking at the rest of the truck you can tell it is cared for.

You're missing my point, the only people that will have these issues are ,....

A) Lives where the road is salted.
B) When people don't take the time to Properly wash underneath if A) is applicable. I don't know how I can make it more clear than that.

If one didn't want to or can't move from places like that then they MUST take the time to clean it underneath better.

If it got in there from spraying off the tires and road, there's NO reason they can't get it out with a spray of clean water from a pressure wand or garden hose. NO reason except laziness.

There is no argument worthy of any more of my time on this matter. I am not and never will be affected by this malady because I choose to live where we don't salt the roads.

Simple solution. Move or do a better job cleaning underneath. End of discussion.
