Here is my 2 cents on the subject....been wrapping Dodge dually's for the last 5+ years for a rodeo promoter in Athens, Tx. The design has to be such that it can be done in pcs. I prefer the material to be 3M 180cv3 w lam. I do the bed and the fender in 2 pcs. I will actually take the bed panel and split it in half in the middle of the bed and give it a small overlap. I install the front portion of the bed first..making sure I match the bed to the cab that is already installed. Next I will work on the fender. Remove the marker lights and lightly prime all the body lines and all edges of the fender where it touches the bed. A second set of hands would be good for the initial set of the panel on the fender.Make sure you have oversized your fender panel....you are going to need it. One you have it in place, squeegee the large flat portions of the fender first...keeping your squeegee strokes in a good level horizontal pattern. Don't try to go to far around the curved portions back towards the bed. If you go to far, you will get into a bind in another area of the fender. Work the lower portions of the fender and slightly feed the vinyl into the body lines...just enough to get it started but not to cause fingers to form below. Now for the wadded up mess you have on the top...take the excess vinly that you have and pull it up and lightly tack it to the top edge of the bed. this will keep the material up and off the fender itself untill you are ready for it. Work back and forth..left and right..a little at a time. I tend to use a heat gun on this because I get more even heat over a larger area. You have to stay pretty even across the top of the fender. Work the vinyl back toward the bed and release the vinyl, that is tacked, once it gets taught. Keep doing this till you make it back to the bed. Let vinyl rest then reheat and rest again before you trim. Install the back half of the bed and post heat the entire graphic.
Feel free to call if you have any additional questions...good luck and hope this helps.
