4wd Question

[Big Red 3500]

Hello,
I have a 2024 3500 purchased new. This is my first 4wd. I have only used 4wd once for a short period a year ago. I don't live in a snowy climate so don't need to use it that much. Should I put it in 4 high periodically and drive it? What is the max speed you can drive in 4wd high?
Thanks for any input.

Do NOT use 4wd on dry pavement.

Don’t use it on dry high traction surfaces, but I would find a dirt road or something to engage it on periodically.
