Review on 🔌 WELLUCK 15 Amp 125V AC Power Inlet Port Plug with Integrated 18 Inches Extension Cord, NEMA 5-15 RV Flanged Inlet with Waterproof Cover and Back Cover, 2 Pole 3-Wire Shore Power Plug for Boat by Andy Jolley

Once you stop drilling a hole in the side of your new cargo trailer, installation is easy. You should use a 2 inch hole saw, no more, no less. I used a small amount of silicone to keep water out. My only gripe, not huge but worth noting, is that they don't have a decorative inner ring to complete the interior. I did it myself but it would have been good without him. For you who just want to dig a hole in the ground and run an extension cord through; This is a much better option and not that expensive.
