This looks like a good deal for a meter that is probably accurate enough for RV use. I might pick one up.

Just remember, resolution does not equal accuracy. Resolution is just the minimum change the display will show. So if the resolution is 0.1 amps, the display will change in 0.1 amp increments. The above specs do not say anything about actual accuracy. Although I suspect the accuracy will be fine for our use.
