I thik the OP said the carwash is on sunnyslope street.
The timestamps on the tracker & the carwash cctv camera seemed to be a few minutes off from each other, but you could pinpoint in the historical data where the RV went by sunnyslope because the previous tracker point is just a street or two prior.
Thanks. Found it.
