I am going to get my first car soon, I am planning on buying a used 1992 Chevy Silverado 1 ton. I found a 1992 Chevy Suburban (Same year by coincidence) and I remembered seeing a website for a company that takes new Ford Crewcab Longbox trucks and an old ford Excursion body and turns them into a 6 door SUV. I was wondering if I could do this with the Silverado and Suburban and come out with a vehicle like this: The only problem that I see is that the truck I am planning on getting is an extended cab, not crew cab. I would just get another truck but I strangely can't find a Crewcab Silverado even though the local craigslist is dominated by 1988-1995 Chevys. This is a picture from the website that makes 6 door Ford "Excursions" (Website: How are the conversions built?) I have no problem extending and strengthening the frame as much as necessary but I would still need another set of doors, I was thinking I could take the small extended cab doors, turn them around, and extend them so I could have the full 6 doors. How easy would this be to do? Any input is appreciated.
