I carry a micro sized Senco 120V 1 gal. It is the smallest brand-name compressor I could find size-wise that was real 120V and could fill a truck tire. It seems to be good quality and is very quiet, I think it was made in Mexico. I have on-board Gen so I wanted 120V.

Not identical to the one linked below but very close (mine is about 15 yrs old.)
