We have an app that the device will be outside. Therefore, there can be a significant, but not rapid, temperature swing. If we go with the internal RC oscillator, is there a temperature range that the calibration will be able to keep the clock stable or like most RC's it is too unstable.

Calibration every 4 s should be sufficient to keep the clock stable for all normal temperature variations, so even outside there should be no problems with this.
