We did it a few years ago with an off road van. Started at Tom Groggin (the closest to the head you can comfortably drive) and just followed the Murray as close as we could to the mouth. It included Wentworth to Renmark on the Old Coach Road and quite a few Ntional Parks. We did a couple of cruises including one at Barmah. I think it was Kingfisher Cruises and was extremely informative about the river. We camped nearby in the National park. We were lucky in that the river level was very high at the time.
Any way just get a map (eg Google) and Wikicamps and go for it.
