Big Truck Rental Peterbilt 520 McNeilus ZR @ ESD

Set out one morning after my neighborhood was collected to see what else was running in the area for the day and ended up finding this rental Peterbilt 520 McNeilus ZR from Big Truck Rental on a nearby trash route filling in for a Rapid Rail. Driver says he really likes it and hopes ESD gets ZR's in the future. From my observation, the McNeilus ZR seems to definitely be a good fit for ESD. I assume they were renting for two reasons; 1. being short on working trucks and 2. trying out another manufacturer besides Heil and Amrep.
