Not sure anyone is against viar as much as they are enamored with 120v units, which if you have a big ol dp or whatever with storage space out the ying yang they make more sense. However for those of us who have limited space, want the convenience of having it all the time even when we aren’t hooked to our trailer (or as op no trailer but a tc) with no fuss no muss just use it as it is always ready to go no getting it out, plugging it in, hooking it up to a battery etc. viar makes some decent units and have some decent reviews. They aren’t the best but they seem to advertise the most and are probably the most heard of and certainly would work for the majority of people. The op has quite a chore going for whatever unit he ends up with as 8-10 tires going from 20 to 80 psi in a 32,33 inch tire is one heck of a lot of air

OP is asking about ON BOARD AIR, not a carry around 120V pancake compressor, nor a pack around weak a$$ pack around 12 volt system. A good 12v on board compressor takes some power, mine can draw 20 amps. My air is ALWAYS with the TV.
Currently I have a bunch of spare payload, but don't want to need a 120 Volt power source. be it generator or inverter. My VIAIR system with 2.5 gallon tank and 12 volt constant duty cycle at 100 psi.
