Chevy Express 4500 Cutaway Alignment

[cegates01]

I have a 2021 Redhawk SE 27N with a 2020 Chevy Express 4500. Anyone have an alignment completed where they were able to increase the positive caster? Local shops have indicated they can only adjust toe. Would like to find out if it is possible to increase caster from 3.75 to around 5.00 positive caster. If they were able to increase positive caster, what did they do?
Thanks.

Your local alignment shops are correct; the Chevy 4500 has a totally different front end compared to the Ford. There is no need or way to increase caster. I had my 22A Redhawk on the Chevy chassis aligned recently for $80 and it drives fine. The only handling part I added was the Roadmaster steering stabilizer.
