Ill be looking for a new truck in the spring. My 02 2500 has close to 400k on it.

I know that the Fords now use soy in the wiring insulation and this has caused problems with rodents chewing on them (I hunt and fish a lot) I cant seem to find information that shows if anyone else does this including GMC.

What issues has anyone has with newer trucks in regards to this
