This mod also has a menyoo version.
If you wouldn't like to install the YMAP or want to modify the map, this is perfect.
Mods like ThunderWind menu(Hopefully soon available) move props around with crazy speed as if there was a massive wind.
If you want to use that, I recommend the menyoo .xml format.

---===INSTALL===---
1. Copy "Franklin's Mega Mansion.xml" to YOURGTA5ROOT/menyooStuff/Spooner (assuming you have menyoo and scripthookv installed)
2. Launch GTA V
3. You won't see the map automatically spawn like in the YMAP, just go to Object Spooner -> Manage Saved Files -> "Franklin's Mega Mansion.xml" -> Load Placements
