I dont know what to say if you have an 2015+ f150. Its going to be a nightmare for you all when it comes time to have collision work done on your trucks. Alot of us have been sent to training on the '15 f150s, but it will be years, yes years before most shops will be able to work on them much. Out of 6 collision centers that we have, only one has capabilities to work on the new fords, and in the whole Okc metro area, there might be 6 or 7 shops. The tools required to work on them are very expensive and you cant use the same tools on steel. Because if worries of cross contamination. Add to that the fact that you cant reuse bolts because their coating is harmed when removed .....your in for a long wait in getting your Ford repaired. Plus just wait for the white rust. I've seen quite a bit of it on some of the lincoln liftgates, plus this will be a problem if the bolts are reused.
Im sure that Gm will use more aluminum like they are saying for the '19 models, but there isn't any major information coming out about repair procedures like we had for a couple years before the '15 f150s hit the lots.
Just make sure you have plenty of rental coverage.....or buy a gm so you don't have these problems!!
