Hey, I'm glad you're enjoying the mod! There is the option to use a mod like universal autoload which can unload the trailer to the side but it would also be possible to move the triggers.
The reason I didn't include it originally was because it would extend the area that needs to be levelled. The levelling is already poor in FS25 so I didn't want to make the problems worse, the building can already be difficult to place if you don't have a perfectly level area already
