Max keeps saying he wants the Rust Bucket back because it has character, but he never says anything about the fact that it has so much Plumber tech installed.
Look Closely: When Ben is eating a chicken leg, he also eats part of the bone.
Look Closely: When Ben is playing the video game in the other RV, he's pressing almost all the buttons and controls rapid-fire, but nothing happens to the ship he's supposed to be controlling.
Pay Attention: The Rust Bucket has several hidden modification and compartments with Plumber technology that the Wrecking Crew never found.
Pay Attention: Everyone in the RV is able to hear the radio, despite the fact that Gwen has headphones connected to it.
Ben: (about to activate Omnitrix) Time for some XLR8tion! (activates Omnitrix but turns into Ripjaws)
Ripjaws: Oh man!
Gwen: And not a drop of water for miles.
Baron Highway: I'm itchin' ta do this!
Turbine: Maybe that's because ya ain't washed in days. You smell more putrid than a possum in a barrel of pickles!
Road Rage: (about the souped-up Rustbucket) Now that's what I call class... with a capital K!
Road Rage: You little brat!
Ben: I know you are, but what am I?
Road Rage: How'd you get in here?
Ben: Forget about me getting in, it's you getting out!
Road Rage: Oh, yeah? How are you gonna do that, sonny?
Ben: Darn! I knew you were going to ask me that!
Upgrade: (taking over the train) What? Never seen a train come alive before?
Shelby: (seeing Ben transform into Upgrade) That's quite the grandson you've got there.
Ben: (after being put through the car wash) Do I look okay?
Gwen: Actually, it's an improvement.
Ben: Uh, I need more ice water. I don't feel so hot.
Gwen: Gee, think it was the fourth trip to the sundae bar, or the fifth?
Gwen: (seeing Ben sitting in the hottub) It's not a monster, but it is pretty horrific looking.
Ben: Forget going up the mountain! We're going down it!
XLR8 - Ripjaws
This is the final appearances of Ripjaws and Upgrade.
Ripjaws' jaws can rip through steel.
We see Upchuck's silhouette on the Omnitrix for the first time.
Alien Form(s) Used:
The Rust Bucket has a top speed of 300 MPH, meaning that it can go about as fast as XLR8.
Upchuck can't digest real food.
Grandpa Max saying the RV has "character" is similar to the Archie comic "Repair Despair" when Archie's dad tells him that his car isn't old, it just has character after Archie's car upset twins Archie was trying to get.
Title Pun: Ben Four Good Buddy
