looks in/through a window at/to/into the back of the RV.

1. James gets up and looks in/through/in through a window at/to/into the back of the RV and sees...

2. James gets up, goes to the back of the RV and looks in/through/in through a window, and sees...

- What would make more sense to you here if James is standing outside the RV?

- Are both sentences OK?

For 1, I would use "through" and "into." You can look "in" or "through" a window, but since you have an "into" in the second part of the sentence, "through" is better. So you don't have "in" and "into," both in the same sentence, which seems a bit like repeating the same word.

For 2, either "in" or "through" works. "In through" seems redundant, though redundancy happens sometimes with us. Since you are continuing to describe what he sees I like "through" better.
