Fab pros, What's your take on this?

I have always wanted a truck like Ak's-r-us was building. I am no where near the metal fabricator he is. So my thoughts are this. Find a 70ish suburban, cut the back off and install a pick up cab back. Leave it a 3 door until I can develop the skill and room to do the build right. What are your thoughts on this? I saw how much work it took to build the crew cab from 2 standard cabs and make the doors open the same way. That is the way I want it but am poor and willing to cut and weld, grind, repeat! Any info/suggestions are appreciated! Thanks Ryan.
