Derpinv and VU-Mod for DarkRP

Hey Facepunch! Was having some trouble and decided to ask if anyone here has a clue.
VU-Mod is a seat addon thing for TDM cars. When having VU and Derpinv installed the ALT-E function with Derpinv fails to work. I hear it is something to do with the hook. I am not too sure how hooks work and how to sort this out. So I need to find out how to edit the hooks for Derpinv or VU-Mod. If you need any logs/scripts to change just ask and I will post them!

It sounds to me that TDM cars might be using the ALT-E Function, I cant really help as I’ve never used TDM cars.
