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?

An inverter would step up not down.

Have a look at this

What kind of phone are you charging? It'll be cheaper to get a car charger that is good for 24v such as http://www.jaycar.co.nz/productView.asp?ID=MP3578&keywords=24v+phone+charger&form=KEYWORD

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.
