About the Peterbilt 520
The Model 520 is a purpose-built low-cab-forward refuse truck whose dual-station cab lets a driver work and steer from either side, with configurations for left-hand, right-hand, dual-seated, and stand-up operation. That flexibility makes it a go-to chassis for automated front-, side-, and rear-loader garbage routes, and the battery-electric 520EV version runs about 80-120 miles on a single charge (roughly 1,100 bin pickups) from its lithium-iron-phosphate battery system.
About the Mack Trucks TerraPro
The cab-over TerraPro was an early pioneer of natural-gas refuse trucks: in 2010 Mack offered the TerraPro Cabover with a 9-liter Cummins Westport ISL G engine rated at 320 hp that ran on CNG or LNG, giving fleets a low-emission alternative for garbage and concrete-pump work. Its Low Entry refuse variant was eventually replaced by the Mack LR in 2018.
