John,
I agree with you on a couple of points. First, the ARB is expensive but built very well. These are the only two ARB products I own, for that reason. It does do tenths of a PSI, so I like that aspect of it. Batteries last a long time and there is an indicator. The built-in deflator button (most have this feature) is handy as well.
I like the ARB fridge but, dollar for dollar, my Truma 60 QT is a better value though not cheap by any measure.
Yeah, anyone fully equipped with ARB and Old Man Emu products has very deep pockets.
Second point, it is getting way off track.
Brian
