I just had the low profile Coleman A/C unit installed (Coleman Mach 8 Polar Cub [47201A876] ). There was also an older version of this unit without the 2 speed motor [49201A876] that used somewhat lower amps.
There is another model that is lower Amp draw but it it is not low profile.
The links below are where I got the info from.
