Yeah I know it's pretty annoying... probably the only solution is adding an empty sub-mesh that shows up only when the vehicle is parked (in this way the vehicle shpuld disappear when parked)... But I don't think I'm going to modify and re-upload all these RVs

These look great, and I love seeing them all over my towns.

I don't suppose there's a way to prevent them from parking in spaces that are too short for them, is there? They park on the sides of roads just fine, but if I use a parking lot or parking garage, they stick out quite a bit.

I'm guessing no, or at least not without a lot of work.
