My truck averages 450-550 pkgs everyday, they gave me a new pick up last week and more deliveries for them (used to be 1-3 packages once in a while), today they got 90+, meaning that because of the holiday my count was 767, the truck is overloaded, the preloader sucks big time, and I have to go back to most of the stops because I can't find all the pkgs, so why would I look for SL when I can only fit so many pkgs in my 12 cube????? Somebody else delivered those today, and they were mad because they dont like getting air and ground at the same time ( used to fedex), thanks to the salesman promising thing that can't be done
