rv extension cord

I am planning a cross country rv trip and need to get a power extension cord. What do you feel is the maximum length I will need? Trying to not buy more than needed as storage is a premium on our 5th wheel.

  • I don't recall ever needing a power extension cord. Water, sure you'll need one once in a while we carry 2 25 ft water lines, and you certainly need extra sewer line. Walmart sells 30 amp extensions BTW.
  • SOW is the cord type and rubber flexibility vs plastic and cost are the main consideration for RVs. Cord weight difference is minor.
  • In all the places we have stayed, we only needed a 50 amp extension cord one time on our 35' 5er. And a 15' cord was more than enough. Our trailer connection is on the rear.

Now that we have a 50 amp 5er, I needed to use the ext cord, but in doing so, only used what we needed to because of lack of avail power supply thru cord. In other words, only 1 A/C unit out of 2 or and water heater. No probs. If we had to, could have switched wh over to gas, and have lil more power to use otherwise. But overall, just have to live within the means of of the 30 amp cord. If a 50 amp ext cord is avail, might be a heavy thing unless a sow cord can be found (just learned of this cord last week).

    They make 50 amp extension cords for a reason. If you have a 50 amp RV it is wise to have a 50 amp ext. cord vs. a 30 amp cord.
    For the OP 25' is a effective length and should ensure you can reach the pedestal. You mentioned storage is at a premium, however it would be silly to get a 15'-50 amp cord because you did not have room to store a 25' cord?

  • Agree with Wiscamper. But at the same time there is always the chance of you feeling the need to say Well Darn... And you need just two more feet... Happy travels.
  • I would recommend a 25' extension cord. Combine that with the power cord from your 5th wheel should be enough to reach the power pedestal. Keep in mind if your 5th wheel is 50AMP the extension cord like your power cord will be heavy.
