Good compromise
Size: 25-Foot, Style: 90° Locking End
I decided to go with this much cheaper version of the same yet higher quality cord from camping world. I really like the 90 degree connectors as these cords are heavy and I did not like the added stress on the RV power connector of the straight connectors. Also did not like the way the straight connector sticks out on camping would’s version so if I accidentally bumped into the cord it could easily be broken. The clamp ring on this one has large lugs making it much easier to tighten onto the RV threads. I really struggled with the ones that don’t have the large lugs. The easy to grip handles are also nice to have when removing from power. My one complaint, the cable jacketing is of lesser quality. You can literally feel the individual conductors inside the jacketing when handling. This makes me feel like this cord will not have the sturdiness to last over time and an insulation failure could be a dangerous situation. If I could get the connectors of this cord with the cable quality of the camping world version, I would pay for the quality.

Great generator cord
Size: 25-Foot, Style: 90° Locking End
I’ve had this cord for 5 years for use with my emergency generator, it doesn’t get used often, but when I’ve needed it it’s been flawless.

Nice item.
Modifying to two male ends, to make use of a built-in surge protector.
