I would buy the aluminum Ford. I think the aluminum will hold up better than metal. My brother has a body shop and rust continues to be a problem with GM pickups. The 99-06 have a terrible problem with rusty rocker panels, cab corners and bedsides. I thought the newer style would not have that problem but I was wrong. The aaftermarket sells rust repair panels for the 2007+GM trucks and my brother has used them on severalChevrolets. The aftermarket doesn't manufacture rust repair panels unless there is a substantal market(same as the 2003+ Dodges). I wouldn't buy the Toyota because they get horrible fuel mileage. The Toyota Tundra and the Nissan Titan use more gas than the other full size pickups.
