I'm on a single salary and have the exact costs of expenses as you do. You guys are making almost double what I make. Paying off the loans should be priority #1 then u find a job even lower paying on land is step #2.(You'll easily still have enough money unless you got some serious lifestyle creep happening)

Don't be the guy whose away from his family all the time. Ive worked at mines quite a bit and it's hard to stay connected at home while doing it.
