I know you were asking 110 vac but why limit yourself to having to use the generator if on the road?
I absolutely love my Viair compressor. I had to go with the 450P because I had tires that needed 125psi (and my pancake 3gallon porter cable compressor couldn't get up past 108). I also like the 100% duty cycle as I fill/check all 12 tires on the truck and camper.
But, there are less expensive Viair options out there.
