I was watching HGTV yesterday and they were talking about installing USB plugs in your home wall outlet. The plugs come with the standard 120 volt plug and also USB ports. They said these have been out on the market for about a year now. I think that's a GREAT idea! Your's is the first I've seen installed in an RV. But there again, I didn't know these even existed until yesterday.
Nice job there. I have additional space in my TT where I could easily install something like that ... actually, several of them. Thanks for sharing!
