Season 4

After Jarrett books a load of monkeys, he learns why they say "never work with kids or animals" --while Marc delivers a load for a Vegas magician and we watch more than his patience disappear.

Chris and Robbie convert one of their rigs to run on veggie oil and end up making a bet with the shipper--beat the tight, cross-country deadline and do it all on free grease. Roy tries to jumpstart his son in the hauling business, but the cab gets cramped when Travis brings along a girlfriend and decades of baggage.

After almost losing his load, Roy's forced to ask Jennifer for help, but gets more than he bargained for when her "favor" turns into etiquette lessons. Jarrett finally gets a new rig, but this maiden voyage might be his last when he hauls some volatile flamethrowers.

Marc's on the sidelines with big rig repairs until his buddy joins in the bidding ... but everyone else gets the last laugh when he's forced to rent a box truck. Chris transports a boat by sea, while Robbie drives by land to the drop off, but things get tense when Chris' cute shipmates seem too distracting.

Chris and Robbie book an easy one day run North of Nashville, but when a bride-to-be insists on coming along, things go just south of hell from there. Jarrett books a load that Roy will take for the second half of the run... if they can find each other.

Marc's buddy, Johnny Chavez finally wins a load, but his day in the sun will be overshadowed when Marc pranks his run. Jennifer hauls a cold, creepy, mysterious load... and that's just the seller, who joins her to ensure the oddity he's shipping makes it to its destination before it unthaws.

Marc drives a load of 20 something's to the "Big Easy" for Mardi Gras, on a run that proves to be anything but easy. Jarrett chases a load because it brings him near a girl he's fallen for and when he runs late he learns love can be costly.

Roy books a complicated Linotype machine, and things get really complicated when he thinks he breaks it in route-but with his skill and welder, he hopes to set things right. After breaking down in the middle of nowhere, Jarrett hatches the brilliant plan of secretly booking himself and the load on uShip! He just hopes that when Chris and Robbie show up, they feel the same way.

Roy lands a wild load of giant, murderous Animatronic Hillbillies, and he almost turns into one himself when he has to deal with the crazy cat lady involved with his side load of cat caskets. Jennifer transports an antique Honda.

With hopes of upping his game, Jarrett joins Marc to learn the ropes on a big rig run, while newcomers Chelsea and Courtney face the deep sea and their deepest fears as they transport a live shark.

Marc is a bit outnumbered when he transports 4 million angry bees, and turns it into a battle of attrition--Marc surviving the bee stings versus the bees jumping ship. We also meet the Bodens and the transporter couple from New Orleans ends up in a mess, literally, when they haul some pristine and not-so pristine dollhouses.

Jarrett seemingly faces the seven plagues and more when he hauls a pedal pub and a side load of sod, while it's almost "game over" for Jenn after she books an overwhelming arcade load with her underwhelming trailer.
