Has anyone shopped around for deals besides what's on Amazon?

We need a 50' 50a cord. Will post here if I find a good deal somewhere.


I built my own, bought the ends and 40’ of 6/4 SOOW cable.

Power Cord Lettering Breakdown

S = Extra hard service (rated for 600V)
J = Junior (hard) service (rated for 300V)
V = Vacuum cord (rated for 300V)
P = Parallel cord
E = Elastomer jacket (UL or NEC only)
T = Thermoplastic jacket
O = Oil resistant outer jacket
OO = Oil-resistant outer jacket and inner insulation
W = Weather and water-resistant - outdoor rated (note: this is NOT the same as Type W, another kind of portable cord)

Based on this, I would use a cord rated SJOW or SJOOW

Here is a link for on line sales of SOOW for $4.83/ft

6/4 SOOW

This is rated for 600v, the "J" wire is rated 300v but doesn't seem to be available.

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...

By the time you buy the cable and the cord body, you would be better off buying a manufatured cable remove the unneeded end. Another option would to buy a range pigtail and use a manufactured 50 amp extension cord.

Not sure about the "E" designation for the outer layer.

This pictured cord is smaller than any I have seen. It came from a Jobsite Power Box. This cord is SOW 6/3 & 8/1. "OO" must give the extra thickness.

These cord caps are good quality, Camco Yellow.

But the manufactured cables are still mostly very heavy and hard to coil up compared to the more supple after market cords you can use. It's more about convenience and ease of use than cost savings.

When I got my RV the store had what I call "Super flex" cords.. My 30 amp cord (it was a 50 amp rig but I had a 30 amp cord for it) was a "Super flex" I used it a lot in the winter even in SC it gets cold "Near freezing" is not uncommon, Freezing happens and "Got to worry about it" well once. and as I prepped it was NOT a problem.

The 30 amp "Super flex" cord.. cold or hot, wound up like a piece of string. real easy.


Home was where I park it. but alas the.

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.
