My son and his buddy converted a ford p/u from 2wd to 4wd. Being aware of my search for the perfect Suburban they insist I can find a sweet 2wd and convert it to 4wd. I scoffed at the idea until I found that sweet 3/4 ton turbo-diesel that would be perfect if 4wd. This is intimidating to me. Is this a reasonable and feasible idea. Thanks.
