Buckland....although it doesn't directly correlate with your topic, I wanted to relay to you that I own two trucks, both Chevys. One 1/2 ton and a 2010 Colorado 4x4. The Colorado has 105K on it, extended cab. It's only a 4-cyl manual transmission. I didn't buy it to put a camper on its back, but I wanted to tell you that truck has given me absolutely NO problems whatsoever. One of the best vehicles I've ever purchased. I have friends who had the 5-cyl model, and they were just as happy.
I think there's an inherent Japanese bias out there, in certain circles, justified by past US auto reliability (or the lack of it). When the Japanese dove full steam into the automaking world decades ago, and pried an opening into US markets, they looked at American technology and figured out how to make it better. Far East countries are pretty good at, and encourage, the economic idea of "apeing" - that is, copying something, tinkering with it and improving it overall. The one difference between 30 years ago and now is that American manufacturers have "aped" Japanese know-how and ingenuity, and the result has been a marked improvement in US autos. So, for what it's worth, don't shy away from American trucks. IMO they're very good. I've owned three and been happy with all of them.
