I’ve read both. In fact, I read Mindor right after Truce.
There’s small references early in the book. That’s it. Mindor is very standalone, you don’t need to read any other EU to get it (though apparently one or two characters from Stover’s prequel-era books appear in Mindor, but I haven’t read any of those and wasn’t lost or confused).
Ok, thanks.
I’ve been reading a lot of post-ROTJ novels out of order, and it has been a little bit confusing at times. I do intend to read Truce at Bakura at some point, but at the moment Shadows of Mindor has piqued my interest a bit more.
