AWD Astros generally have more issues?

Looking to purchase my first Astro van, and have located one fairly close. It is an AWD with ~130,000mi.
My plan is to lift it with larger tires. It will be an occasional family mover, not an exploration vehicle. I understand AWD is not needed for my application.
I have heard the AWD vans have more issues - this makes sense as there are more components.
If this is true, are the issues usually big deals or small things? This specific van is a ‘99 model. I like the idea of having AWD because it opens up options if I ever do get adventurous. Small chance, but we also have the occasional brutal ice storm in my area. Again, small chance. Just sharing ideas that I like the sound of an AWD, but would like to hear if this is hundreds more per year to maintain, or usually just smaller items.
