I am purchasing a 50A extension cord for our 2970RL. Our power cord connection point is mid trailer. The OEM power cord extends about 6 feet beyond the back of the TT. This summer we will be heading to some areas to the north and northeast and I know the hookup locations can be unpredictable and poorly placed in some of the parks we will be staying. I have looked and I am leaning towards a 15-foot extension cord. Primarily because 1) I think another 15 feet would be sufficient (of course until it's not), and 2) the increased cost, weight, and storage requirements for the longer ones is significant. Appreciate any feed back on what lengths you have have and what is really needed.

15 foot = $65.00 and 30 foot = $102 - is the extra $40 needed and not to mention the additional storage requirements and weight for a 30 foot.
