I have seen a lot of posts and a few reviews of the new ArkPak AP730 in Australia, and mentions of an AP735 coming soon. No specs on the 735, but the 730 boosts the charging amperage, and more importantly doubles the inverter size to 300W. About to buy another ArkPak for a new trailer build and am obviously holding out for the new one, but want to know just how long I have to hold out. Emailed ArkPak in the US a few weeks ago but they haven't replied. Anyone know anything?
