Creating Custom tow truck file

I'm trying to add this tow truck to the game...and i'm not sure I'm getting it right, so i want to ask before i complete what i'm doing...so i don't mess up my game. So this is the one i want to add https://www.gta5-mods.com/vehicles/els-fivem-international-durastar-flatbed-candice_211, and it doesn't come with any meta files. So if I'm remembering right, there are 2 ways i could install this...first would be to change the file names to Flatbed, and just go with that...or, add as a separate truck, and copy the vehicle.meta for flatbed, change the name to dsflatbed, and then just use like that? And then to get them to respond for tow requests i'd change the name in my ini file to dsflatbed. If any of that doesn't seem right, let me know? Thanks for everyone who looks and helps with my question...along with answering all the questions you can.
