Check this Erica...208 hp capacity, MONSTER power capacity, all-metal construction. I dig how Erica goes all out on their power, also...very beefy 2.5A on each 12V rail, split as 1.25A for upper and lower since they use these integrated P/S + busboards, which is another plus as you don't have to worry about DC wiring inside the cab coming loose in transit.
