First, thanks for all replies.
dalenoel, that cord looks like a possibility. Have you used one like it?
Ranger Smith, I saw that cord and it looks like it would be flexible in cold weather, but I don't think that company has 30 AMP cold weather flexible cords.
BB_TX, hello to a fellow Texan. Somehow we must have different cords. I bought a 30SPP.RV cord and it is really not very flexible at all in the cold weather we have been experiencing lately (say 40 degrees). I know Marinco is reputable, but this time they did not deliver to me what I thought I was going to get. Or maybe I ordered the wrong one?
There's lots of advice and information in forums...
sometimes it is correct.
