I can't say what it will cost for a Dodge, but we had three new F350s converted a couple years back. The local Ford dealership wanted $7000. Not a typo. I'm guessing that they were just going to replace the doors. Our boss found a local place that did them for around $3500 each. Again, not a typo. It was a nightmare. The windows and locks gave us constant problems on all three trucks. There is nothing quite like a 300 mile drive in the winter with the window stuck open or having to use the key to lock the doors after paying $3500.
We were much better off before the "conversion".
