Aluminum is a wonderful material...when used in the right places...even 'Military Grade'....which is pure marketing verbiage to play to those who are ignorant on that matter. Like anything that is used in the 'Military' can be labeled "Military Grade"...toothpaste/buttons/shoes/plates/paint/etc used in the military can be labeled "Military Grade"... :S
Anyone have a set of aluminum sockets?....or aluminum chisels?....how about aluminum lug nuts?....or aluminum grade 8 bolts?....or a wood burning stove with an aluminum fire box?....or an aluminum barrel for a 44 mag?
There are perfectly GREAT places to use aluminum, but IMHO, not for a pickup bed used for work...okay as a pure boulevard cruiser pickup that will never see a load of gravel/cobble-stones/bricks/etc
PS...what are the GVWR's and GAWR's of these two pickups in discussion?
