what is the best generator to buy if I need to run 13 500 A/C?
Lots of good comments on this string. If price is no object, then I'd go with two 2000i Hondas, Yamahas, or Champions in that order. Hooking two in parallel will give you the power you need, with the additional advantage of easier carrying. As for me, I would be hard pressed to move a 3000i unit of any manufacture out of the bed of my truck. Much easier to do this with single 2000i units. You also have the advantage of using only one if all you need do is charge up the batteries or run other, lower power AC appliances.
As for us, we have had a pair of Champion 2000i's for a few years now and have had nothing but good, reliable service. At a cost less than half of what I could find for a red (Honda) or blue (Yamaha) setup, I haven't seen the value in paying the premium. JMHO.
