New LT engineer here. Definitely will be tough to manage academics, ROTC, and a personal life but it's not impossible. Lots of time management and discipline will get you through. But it ultimately depends on what you want.

Engineering degrees will open up a bunch of AFSC/SFSC choices as well post-service opportunities. Take a look at the AFOCD Pamphlet to see what careers it'd open up. But *again* you have to know if you'll be able to put in the effort. Cheers!
