If it was my money and I was looking for an off-road toy. I would sell the Raptor, buy a XL or XLT 150 with a v8. Then build it into a long travel supercharged truck. Or find someone who started a build like this thats for sale, buy it and finish it.
But if I only did mid off-roading and wanted resale value, I would get the Gen 3.
