What are you going to install into your Isuzu Rodeo (RA, RC)
(we need this information to establish the correct parts needed)?

The Isuzu Rodeo nameplate was used on a variety of vehicles in different markets, this pickup truck was known in some non-European markets as the D-Max.

It was sold in Australasia as the Holden Rodeo from 2003-2008 and later as the Holden Colorado from 2008-2012, during which time Isuzu also sold the nearly identical Isuzu Rodeo in this market.
