I have boondocked extensively in the past....not so much anymore. So I feel marginally qualified to say:
The accuracy of a meter is really not critical for any RV function.
The difference between 3/4 full black tank and almost full is meaningless. When it reaches that stage your next step is finding a place to dump.
the difference between a meter showing 12.5 volts and another one that shows 12.4 is nothing to worry about. Most seasoned RV boondockers can judge the battery condition by the brightness of the lights :)
My AC meter is off by about 3 volts when compared to my Fluke so I just do the math when I look at it. I'd rather spend my time worrying about whether or not the fish are biting...
Every RV'er is different with different needs. Most probably have no interest in or need of tools like this. Some of us however enjoy the technical aspect and find this kind of stuff fascinating. Certainly no one ever suggested that you are "doing it wrong." Obviously since you've boondocked a lot in the past, whatever you've been doing has been working for you.
Personally, my ONLY complaint is when I'm camping next to someone who is running their 5KW construction generator for 6 hours a day to charge at 5 amps through their Wiffco! :S. Then I'm not a real happy camper. :M
