I'm still running the in-cab tank and I do not plan on relocating it. The two concerns that I see most often about the in-cab tank center around sound and baffles.
I have run it below "E" on the gauge and have not experienced fuel starvation or pickup problems. The tall, narrow shape appears to have negated the need for baffles.
For sound, I made sure to buy a genuine EP381 AC Delco pump (watch out for the cheapo gray market knock-offs on eBay). I wrapped the tank in a layer of Dynamat Extreme to add some mass and 1 layer of Raam Audio's self adhesive Ensolite foam. I can't hear fuel slosh in the tank at all anymore. The buzz of the pump is very faint. I can hear it with the truck idling, but the road noise drowns it out at anything over 15 MPH. With the windows rolled up and the AC on, the evaporator fan is all I hear, even idling and sitting still.
