I know the trend is for open under tables.
I built the "Revolutionary RT from the 1995 AW mag. in 97, it's modular, the table cab and cart disassemble in a couple mins, no hardware required and I have -0- regrets. I used to bring the table to jobs; I always had crap on the router and lift when open to the weather.
I don't have an issue with a router in a box for a couple reasons; my shop is so small eventually I'd probably have smacked the router and or lift with stock when flipping it around for whatever reason.
Maybe 20% of my projects require me to remove the fence and DC attached to it, the enclosed box, baffles and the DC mounted to the back of the box draw the chips and dust away well enough not to require constant dust offs, I maybe blow/brush debris from the lift 1 - 2 times a yr.
Never bite the hand that looks dirty!
