After blowing two car chargers in as many days, it seems my new work truck has a 24volt ciggarette lighter.
Does a simple 24volt to 12volt inverter solve these problems or do I need more drastic steps?

Yes you just need to step-down from 24v DC to 12v DC.  But you should select a step-down converter which is specifically made for automotive usage, because they have to withstand the high transient voltage spikes that the vehicle's electrical system may produce.

Almost all car chargers I have seen have been specced for 12-24v operation. Suspect there is something else going on causing the problems.
