We have found ourselves in a spot where we are going to have to live in our camper for a bit and need to purchase an extension cord that will reach the closest power. I am looking at a heavy duty 100...
If no AC, portable heater, or microwave, then a good quality 12 ga. is suitable. If you use the microwave, it might struggle with low voltage or amperage. You can definitely tell when that happens. 12 ga. is about $100 10 ga. is about $150. Both are extension cords with 15 Amp ends at Lowe’s. Me, I’d go with 10 ga. because I could repurpose it later.
