I also like Jerry Marsden's book and taught from it to high school students once. It is quite mathematically rigorous however. The Kline approach, where the subject is lavishly explained intuitively, non rigorously, and at great length, as well as illustrated physically, seems not to be easy to find. A review I read of his book called it something of an out of date book and rather unique, though the reviewer liked it for its intended audience.
I wonder how you like the first three sections or chapters, of volume II of Feynman's lectures on physics? He seems to take the approach of not assuming you know the calculus, and explaining it from his, the physicist's, point of view, pretty much from scratch. Hence it is actually harder to understand for me, a mathematician, since it is not theoretically precise enough for me, but may be easier for you since it is tied more closely to the physics. Perhaps I should say that the reason it is harder to understand for me, may be that he is asking me to understand more, not just the math, but also the physics behind the math. For you that may be a plus. It's only 35 pages but gives you the main theorems of gauss, stokes, and so on.
