You're right to be making sure of the size required. It's very easy to end up with the wrong size if you're using the overall length not the shell length.
Not all bad though, we ended up one size too large for our 19 but now that it's on our 21 it's a perfect fit.
I notice that the rvcover website lists the cover size under the main body of the text.
For the 14'-16' size the length is listed as 198", 16.5'. Measure you shell length and that should give you pretty good feedback on the suitability of that size.
Going larger lets you completely cover everything, including the tongue but the downside is that the fit can be a bit floppy and require some straps to prevent billowing out in wind.
