Good luck finding any meter, even a good Fluke meter, that will directly measure 30A DC or AC. You could simply run your current through a shunt and measure the voltage drop across it and figure out the current as discribed above using Ohm's Law.

In the 10+ years I have been repairing and calibrating electronic test equipment I have never seen a voltmeter that measures Peak to Peak voltage. Every meter I have ever laid hands on has been a true RMS meter. You can purchase some of the new Graphical meters made by Fluke which measure RMS voltage and will convert it mathimatically to a Peak to Peak value...it does not however acutally measure p-p voltage.

If you do decide to use a shunt, or resistor, make sure it is big enough to handle the power running through it. Too small of a resistor and you will let the smoke out of it really quick.
