How much would it cost to fully restore a Ford F 150?

My uncle owns a Ford F 150, he really loves his truck but in recent years due to his failing health the truck is not doing too well.To repay him for all the things he's done for me over the years I want to fully restore it. The truck works fine mostly, with some trouble from the brakes other than that and a failing paint job its in good condition. One of the main things I want to get done is a wolf design on the tailgate. Any general ideas on the price? I'm pretty flexible with it.

A full body off restoration and updating a lot of things is probably about $15,000 to $20,000.

I'm doing a full restoration on my f 150, I'm about 3k in and all that's left is to paint the body panels and put them back on… I have no idea how Larry got 15k… If you get the tailgate professionally done, and do everything else yourself id say you would be around 6k at the most
