We don't have contracts with Walmart for distribution runs. One-offs happen, just like how Knight Refrigerated has hauled Swift Reefers before, because the load was loaded in a Swift Reefer by the idiot lumpers at the dock, they wouldn't reload, and we just crack dealed with Swift to move the load.
Walmart contract loads are pains in the dick and there's a reason Swift, Crete, and CR England pull them instead of us. Not much in the way of miles, shit detention (Walmart gets 4 hours to unload us if it's a live unload, and us drivers don't get detention pay for sitting for that 4 hours either) and Walmart derp oversight which obviously doesn't help.
Working for Walmart isn't all it's cracked up to be either. The pay is high, yes, but their equipment isn't as immaculate as you'd think, the shifts aren't that great and primarily slipseating teams, and with the timelines they have, they're more hammer down and derp than Fedex or UPS, just minus the wobbly wagon effect.
Never want to drive Walmart any more than I already do, delivering at DC's.... and most of the DC's are derp as well.
We have Knight Pete's on dedicated Cummins runs with Cummins trailers.
We have SAPA logo'ed, Operated by Knight on the side, grey trucks with covered wagon flatbeds for their dedicated runs.
We have Amazon logo'ed trailers for dedicated Amazon Prime stuff pulled by Knight trucks.
Then we have our standard dryvans or reefers for everyone and everything else. We have some dedicated runs, but most companies don't have us dedicated enough or want to pay the extra to throw their stuff on the side for the contract length they are working with.
