Can you unload and load up a boat on a trail er in gta 5?

Yes, in GTA 5, you can load and unload boats onto a trailer. To do this, you need to back the trailer close to the water and then use the boat to drive it onto the trailer. Once the boat is on the trailer, it will automatically attach, allowing you to transport it. Just ensure you position both the boat and trailer correctly for the loading and unloading process to work smoothly.
