AIO husband wants new truck, I want debt paid off first

For back story, my husband wants a new vehicle. It’ll end up being over 800 a month, with a trade in.

The last new (to him) vehicle he got about 8 years ago now. It just truly sits in the garage because right now, he drives a company truck for work.

He’s been wanting a new vehicle for awhile. (Nothing truly wrong with what he has now, he’s wanting to trade it in and get about 6k for it)

Am I overreacting by wanting to pay off the credit card debt he has first before he dives into another huge bill?
