MCG Proxy Vehicle
Naturally, only use for Previs... Drag Vu_ProxyVehiclePresets.ms into viewport for Presets, will set your currently selected vehicles.
ver 1.01: added Chassis Keep Level option, ie. for different wheel sizes, you may keep the chassis level with either the Back or Front wheels (plus Hover), otherwise different wheel size will affect chassis angle....like on a wheelchair or a dragster...get latest Presets for more...
