Here is my revised list:

1) F150
2) Chevy
3) Ram
4) GMC
5) Toyota

GMC and Ram get demoted.

GMC gets demoted for the Government Motors Company decals. I won't drive a truck that reminds me of Government Motors every time I see it.

Chevy is above Ram because Ram is now Italian owned. Chevy, although part of GM, is at least an American brand.
