Those are cool looking, but I dont ever use my Frunk. Even though I know how to close it, I am scared to use it in case I put a huge dent into the flimsily aluminum. I'd rather use all my other storage first.
Come to think of it though, I do think I have a 50 foot 120v extension cord up there from my last road trip. We were staying at a hotel that had only one destination charger available and wanted a backup in case it wasn't free when we got there at 11pm. Thankfully it was, so I never used it and forgot about it.
