Head over to the Lightning Forums. Every order on Wave 1 has been filled. While Ford did not specifically make an EV chassis for the Lightning, they did work on making changes to the body. The F-150 rides like a Luxury Car and I believe Ford just wanted to use this generation as a test platform on an already great product. The next gen should be out in 2025 on its own platform. Basically one year after the Silverado and CT.
I'm on the waitlist and haven't heard a peep.
The F150 is not the best riding pickup. I've test driven them all and the Ram's coil over springs rear end is known to be the best riding but even then it doesn't ride like a luxury car. Not sure where you got that.
