Love dealing with etrailer! Their support is the best I’ve encountered. The RV power extension is perfect and I have used it in several occasions now. They are my resource for all RV parts. Quality and good prices.


Cord came quickly and nicely packaged. Plugged it into my camper, into a pigtail, and into my generator. Worked perfectly.

No problems. Plug it in, and it works. Nice, heavy duty product.

Great to work with. |I had ordered wrong cord and they sent Return label right away and helped me order the correct cord.


Perfect OEM replacement


Works as advertised.


Any product that i have bought in the past has been exactly as i wanted, the light harness i bought for my Jeep works well the light bulbs are not very bright, but easily fixed


just what I wanted. Quality 30 amp extension cord


Would love to give a 5 star put at this time i can not, Was about to cancel this order until i got a Email saying it was finally shipped Put decided not to cancel even thro i had to borrowed a 30 amp ext cord,Part A10-3025E was out of stock,the most important part i needed in the whole shipped,to late to used my new 30 amp Mighty core rv power cord extension this year,But i am shore it will work great next year. The rest of my order was Great.. the triple ext cord,the sewer adapter,the pop up container.and the septic treatment worked great,Now the Question is would i prefer a friend and would i order again from Etrailer,com.The Answer is YES They just have to let you no when a product is out of stock,The Product are great at a great price


Extension cord is heavy gauge and appears to be well-made.


Bought this for my camper about a year ago no problems with the cord. ordered and received in a couple days. will use etrailer again.


The perfect adapter and extension cord for my RV. My rig is set up for 50 amp service however, this is not always available in a number of campgrounds. 30 amp is more common, therefore I can run most everything in my trailer!


A 30 foot power cord came with our travel trailer. I had a feeling that this might be short in certain instances. I have needed the extention cord about 50% of the time. Glad I got it! Works great, and very flexible.


This 30 amp cord is just what I needed. High quality, coils up every time without an issue.I it's way better than I expected for the price.

Great quality . I have used the extension many times with no problems
Eric L - 09/03/2017


I use the cord with the existing cord as an extension cord. It allows me to camp further away from the power supply. Also, when running on generator, I can move it further away. Great product & great price.

by: delivered as promised, great service. Will follow up with a review on product once it is used a number of times.


This cord is exactly what I needed. Now I am set. Another great purchase from etrailer.


Heavy duty 30 amp extension cord that was exactly what I needed! Shipped super fast!


Just as described in perfect condition and shipped very quickly! I will order again from etrailer!!


Everything I wanted it to be.


This product is just what we needed our cord was not quite long enough for where are camper set now with this extension we have plenty cord for our needs


I had a hard time finding this product. Etrailer delivered thanks!


Its a good cord. Nice and flexible and very durable


needed a longer cord for the motor home. This cord was perfect for the job.


Just what I needed at a decent price.

should last almost forever.
