I love runners too but this does nothing to negate the fact that it is a truck chassis with a different body. Basically you gain no width benefits at all compared to most other options out there.

If the runner is in the options then stay away from the V6 models period, they are crap engines prone to sudden and painful failure of the headgaskets, in fact you can pick them up all day on CL for a couple grand for newer models full options and blown engine if you want to take the tie to swap in a 4.3 chevy which is really a simple and reliable swap.
