Would like some advice on investments.

I am currently in the military and my wife is working bringing approximately 4.5k per month. I am investing in my retirement roughly 400 per month.

My big question is. I have a reliable motorcycle on a loan,as my daily driver, a truck bought outright for 4.5k that I am working on and have at this point out in ~500 bucks to fix up. We have a 2019 Subaru forester as our daily driver and her driver to work vehicle. I have 30k in savings and my income and hers covers monthly expenses. I would like better direction on what exactly we should be doing with our extra income. Thank you for responses in advance.
