The biggest issue with GTA5 is that everything is very fragmented. There are around three or four ways of installing a vehicle modification, for instance. You'll be able to discover these with some searching on here or somewhere like YouTube if you want a video tutorial.
 
Our solution -- Lenny's Mod Loader -- aims to simplify installing vehicle mods and mods where content needs added to the game (like Coastal Callouts). Most compatible mods can be installed with just a click or two. You can find LML compatible mods in our downloads section.
 
For most script mods, these tend to be quite easy, you typically drag them to your GTA folder. Making this any easier would be lobotomising the process. LSPDFR for instance does even have an auto-installer.
