Trailersaver's can be bought with a compressor but they are a 12v unit NOT engine driven.

Trailersavers can be ordered without the compressor and you can fill them the same way you would your Trailair pinbox but the compressor option is much more convenient as you would then have a rocker switch with guage that would allow you to add or exhaust air simply by moving the switch and watching the guage.

The thing to watch is; make sure that the compressor that comes with the unit is rated high enough and with enough CFM's to enable a quick-connect fitting to be used to plug in an air hose to add air to your trailer tires or suspension also.

The Holland-Binkley head is patterned after the commercial big boys and is probably the easiest hitch to operate.

The arcing moment of the Trailersaver is less than the Trailair and will not be complicated by the tendancy of the actual pin to be angled when the lower jaw of the Trailair is all the way down. A standard pinbox will always have the pin in a fixed vertical. Fore and aft tugging will not be as pronounced with the Trailersaver as the hitch head will not have to tilt fore and aft as much when the Trailersaver is moving up and down as it would with the movement of the lower jaw of the Trailair pinbox.

This tilting fore and aft is less noticeable the heavier your truck is as the laws of inertia will apply. This fore and aft will also be directly related to the amount of distance from the two pivot points on either side of your actual hitch head to the top surface of the head's plate.
