The new ones are, Dave. Those are the ones with the R-134A and shore power option. The Proheat Gen 4 (which I believe Jenny & Nick have) is 3500 or 4000 watts. That CCU can pull almost 3000 by itself with the compressor, blower fan, and condenser fan. The new ones are slightly more efficient CCU's.
The stock alternator is a 40 amp.
