That’s about all you have to do. I would shop Craigslist for a converter. Keep it simple and keep the cost down. You can always add, if you decide you want to go higher tech like some of the folks you read about here or in other forums.
Remember you will not see the amperage you get from the alligator on the battery. Amperage down the charge lead from the truck is quite low, so if you are thinking you need a to make other changes which add amp draw from the battery and will not be living on the cord often (plugged in), that is something to consider. 🙂
