I'm stoked you like my high top idea. Steve seems like a legit dude and i would love to know how the top turns out as i will be following suit this fall.
To charge your batteries with the campsite power you'll need an converter/charger. Its a standard item on most rv's and you could probably find one used out of a camper, or pick one up new for around 500 bucks (i'm looking for a used one).
The seat hinge your looking for is here: http://www.justkampers.com/shop/rock-an ... 11561.html
I know an american company does them as well, just cant seem to find them right now.
I'm travelling for the next week or so but will try to answer any questions if i can.
