My trucks use an older chassis and I am very well versatile with that chassis so it is not up to current Roblox standards. The density of the chassis must be changed to a different value. Refer to this document to see what needs to be changed. https://docs.google.com/document/d/1vu3dYmEZPcSVliMHpvXLBkYucX3oSvKgvMAxogY3lUg/edit?usp=sharing

For the people who have bought my forklift or telehandlers, I RECOMMEND TO CLICK THE PALLET ONCE THEN LIFT, THEN UNCLICK AFTER. After doing this, you can lift all the other pallets freely, With this network ownership it could probably be okay for highly optimized games. These Pallets are light enough to be picked up at the start but I wouldn't recommend. If the pallet starts following you, you forgot to unclick it. If you are using the forklift/telehandler in a high performance game, I recommend you click the pallet and then lift it, once you have done that unclick it. This applies to my hay squeeze and farming loaders as well.
