Sliding 5th wheels?

[Espeefan]

I'm at the point in my KW build where I need to mount up my 5th wheel plate. I've been thinking of different ways to do that, and I'm considering making it a (manual) slider. The question is whether or not it's worth the extra effort on a model truck. Chances are I'm not going to slide it around much, but the cool factor and adjustability would be there, if I ever needed it. What do you guys think? Do it, or not? Seems almost everyone has their 5th wheels centered over the drive axles, if not slightly forward, but once it's set, that's pretty much where it stays. Beyond picking up a little traction on the steer wheels, I don't think it would be all that beneficial for a model. We don't seem to be to concerned with fuel mileage, ride comfort, and axle weight requirements!
