Great Cord and Great Price
Size: 30-Foot, Style: Standard End
I got an email from Camping World telling me about a sale on these extension cords. I looked at their site and they wanted about $140. I really needed the cord and almost ordered from them, but I checked Amazon first. Surprise: It was lots cheaper here. Yay. Deal done.
This is a great cord. My stock 50A power cord that came with my fifth wheel is too short to reach to my house and plug in and charge my coach batteries. I've used other extension cords, but they sometimes get hot--especially if I don't completely uncoil them. So now I use this Camco extension to reach the outlet in my garage. Even though the garage outlet is only a 20A breaker, it's still a more efficient charge and safer connection to use the stock cord, plus this extension, plus the dog-bone adapter to reduce down to the 110 outlet. The connections are clean and I get the best charge I can possibly get from that outlet. As long as I don't run the air conditioner or any other heavy appliances, I won't trip the breaker in the house panel.
This cord is constructed well. The ends are good and easy to plug/unplug. The Velcro carrying handle is a big help too. Well done.

Honestly. Hope for the best, will update...
Size: 15-Foot, Style: Standard End
Durable solid high quality built. Got a 15 ft and the length is perfect. It's so heavy, can't imaging if I have got a 25ft or 50ft one. I bought it because of its using 6 gauge wires, and 8 gauge for the ground. I am using it on a 40a circuit breaker and running on a 8 gauge wire from the breaker to the NEMA outlet, so limited it to charging the EV with 32a max. Not expecting it to be heating up the wires or burning the heads, will update this posting if it does.
May 20, 2025 update: solid build cord, very durable. It does a perfect job what I have expected. The head feels just slightly warm with my setup. Glad that I bought this.

Simple install
Style: 5th Wheel Stabilizer Tripod Jack, Pattern Name: Stabilizer
Simple intsall, easily adjustable to diffrent hights, feet have a nice base so they don't sink, but can be placed on pads, helps with stability. Quality seems to be good. Nice weight not cheap and flimsy, durable enough to do the job, but not so heavy you need two people to move it.
