For your 2002 Isuzu Rodeo the trailer kit I would recommend is the T-One kit part # 118360 which is a confirmed fit and installs by plugging inline with the vehicle taillight connectors. I attached an install video for this kit on a similar 2001 Isuzu Rodeo for you to check out as well. view full answer...
Since you went to a taller vehicle all you need is a drop shank for the weight distribution system like the part # EQ90-02-4400 which will give you the ability to lower the head of the unit so you can tow the trailer level. view full answer...
