GM's Campaign Against Aluminum

I still wonder how aluminum will hold up. Corrosion, accidents etc. If I recall several years ago another industry went aluminum. Wiring in mobile homes. Lots of mobile homes burned down until they got it right. Aluminum won't rust but have you ever seen aluminum skirting on mobile homes in the AZ desert? It just disappears where it comes close to certain soils. Deteriates faster than rusted steel. Like to see the chassis in 5 years. Take a look at some of the first horse trails built with aluminum. Falling apart. A PU gets used off road where these harsh dirts etc. get up underneath. Not like a Corvet driving down highways. Maybe that is GMs plan. Wait and see. I only buy Fords but I'll wait and watch.
