I think whomever told you your AC unit pulls 30 amps is totally wrong.. It probably pulls in the area of 15 to 20 amps. Just a guess but I am sure its in the ball park.
For an inverter you need to do the math but the formula is P/VxI . "I" being current, V being voltage and P being power.
I am thinking in the area of 1800 watts power or a little more just to power the AC unit. Now you need a inverter to produce a minimum of that amount of power. Thats a lot of power coming from your alternator and battery. Probably max it will produce.
A small onboard generator would probably be best.
BTW if the unit truely has a 30A draw you need to double the math above. I only figured on 15 amps.
