All the RV power cords I've seen are S, not SJ rated. In any case, look for rubber or SE--- designations. Cheaper cord will be thermoplastic (ST--), stiff in cold weather. Rubber & elastomer (the E) are much more flexible. For example SEOOW is a good choice. Stay away from STOW and the like...
SOOW is by far the best choice, we full time our cord has seen heat and direct sun, cold and covered with snow, and a slightly flooded site and been under water (cable only not ends). The cable is still as good as new and still easy to coil into the 3 gallon bucket when travel.
It would be interesting to compare our cords side by side. Yours has inner insulation designation “O” and mine does not. I believe mine is a smaller diameter as my ground is #8 and yours is #6 and without the insulation it makes mine smaller. Will this may make it less durable? I don’t know but I do know the conditions my cord was designed to handle on Construction Sites and no doubt is more than needed in the RV world.
Ron, yours might be a bit smaller, but I can't describe the thrill when I grabbed my 3 gallon bucked and started coiling the "New" 40' cable in it and it all fit! That was a great space saver over the old cable!
The old thermoplastic cable was only 25' the new as stated is 40'.
