I have tried 12 volt and 110 options. I have a tundra with an optima yellow top in it... for 12 volt I have used an LVM for about a decade, and then it puked it burned up the switch and I found a rule knock off, and it puked a bearing. The high pitched whine is enough to give you tinitus. I have also run an airpig, and the NRS knock off of the lvm. all meh. Back in my guiding days we ran a man-of-rubber pump of a Genny, and we could do 14 boats, and very little top off. depending on the statute of limitations, we may or may not have held the blow-off valve in so we would not have to hand top.
My current set up is the top half of a craftsman shopvac blower run through a 2800 cobra inverter. I took a set of 8 gauge jumper cables, cut the handles off one end crimped on lugs, and that rocks. My buddy just got a high flow dog drier and it has impressive stats, so we will be trying that with the inverter too.
I think 110 is the best way to go, I also think there is a theoretical limit to how many CFM of air we can fit past a leafield per minute!
