Yes, it is but I'm going to do a couple of "upgrades". The cup holder is not strong enough to carry anything more than a small cup of coffee, it's works better as a stabilizer for a tall, narrow cup that eventually rests on top of the hand brake lever. As such, the cup goes up and down when you put on the hand brake (minor, I know, but a bit of an annoyance). I have the 12VDC plug on the bottom left side of the front panel. An accessory plug in this position gets pushed around a bit by the cup. To solve all this, I'm going to put in a small cross member between the side panels, at about the height of the hand brake lever in the up position. The cup should rest on this and be stabilized by the upper ring
