And now I will tell you about one useful accessory that can be very helpful on the road. This is the GearIT 30A extension cord. With NEMA TT-30 connectors on both sides, this extension cord allows you to connect your motorhome or trailer to an external power source up to 10 feet away. The connectors themselves are designed for reliability. Now you don't have to drive up close to a pole with an outlet, for example - just pull over nearby. The GearIT cable is easy to reach, and 10 feet is often enough. So if you intend to travel with a trailer or RV, I recommend getting this useful extension cord.
