Keystone didn’t put any electrical outlets on the slide-out, which is pretty silly. So I decided to put two receptacles in myself. I’m not sure what this does for the warranty but I reaaaaally wanted power there. I bought a bunch of parts and did a pretty clean install I think. Plus, I have 2 USB ports at each receptacle that are 4 amps each. Saweeeet! Please take a look at the installation in the Upgrades section!
