A Big Fat Road Vehicle Set
Road Hog is available from the content service in OpenTTD, as a zip for manual installation, or as a source checkout for compiling locally (requires mercurial and various python dependencies).
A few things to know before setting up a Road Hog game...
Road Hog will disable all the default OpenTTD vehicles.
There is a parameter to adjust vehicle capacity up or down from the default. This will apply to all vehicles in the set.
There are no known conflicts between Road Hog and other NewGRF sets.
Vehicles are introduced between approximately 1860 and 2007. OpenTTD randomises introduction dates, so these may vary a little.
Every cargo in the game should be supported by at least one vehicle in Road Hog (from 1860 onwards). Report back if it doesn't.
For certain cargos, some vehicles will show accurate cargo graphics or different liveries.
