I think the 18" wheels are a really great looking wheel and look just right on the 1 Ton. The tires are more expensive than the 17" but are also taller and give you a couple of extra mph on the top end if your motor is up to it. I think the front axles are the same on both your trucks, just using different hubs depending on the wheels. I was thinking that Mar-K manufacturing would be able to make a wider front panel and tailgate for an extra wide box, as well as supply extra strips and pieces of wood for the bed.
