One option is to hunt down a (used/refurbished) utility company meter. They aren't too hard to find at reasonable prices because many many utility companies have transitioned over the past several years to meters that can be read remotely rather than by a meter reader. These are quite accurate.
Another interesting option, assuming it is and does what it claims: Neato AC panel meter! At that price, I think it would be worth trying out...very tempting.
That looks like an interesting device, but only appears to be able to handle one wire (maybe less than 4/0 from the pics). For a 30A RV service not a big deal since you only have one hot leg to have the current sensor to go over. A 50A RV service or home may be a problem.
The other device looks good, but you should compare it to a known accurate measurement device if you want to use it to argue that a park's meter is off. Some companies do provide calibration reports with their equipment.
Agree, that unless the parks meter was off a lot, it wouldn't really pay for itself at nearly $250. Either way, even a good used meter needs to be tested periodically to make sure it's registering at a least a 95-105% level.
