26 wabash slim 4 months ago BZ, I haven't opened it up. I kinda don't want to know. I should want to know, though, shouldn't I? Maybe I'll look. But I have my doubts.I wish it had chrome ports too, they're cooler.Slim it's not hard at all to move. Kustom had KILLER ball casters, as I'm sure you remember. It just gliiiides. You have to tip into and out of the vehicle, protecting the down side as you slide it. Oh, and it doesn't do stairs. Elevators are fine. Plan ahead. I'm well aware of casters and wheels and elevators, Proteus. It's when you don't have these things is when you discover the problem. Our theater had 100 steps from the main floor to the attic. Did that trip 24 times in one day, hauling stuff both ways. No elevator in the building save for the orchestra pit. I'm on first name basis with my chiropractor.
