The Burb is body-on-frame, so likely does not have the nice square, flat, floor pan the RVibrake was designed for. Doesn't mean it won't work, but probably not as nice a fit as in the video. Most unit bodies have a ridge molded into the body across the front of the seat area, for general stiffness and to support the seat. Typically a couple inches high, which may not always be enough to firmly stop the RVibrake when it butts up to it. Especially since it often is somewhat rounded and has a thick carpet over it. Note that the pseudo-pan in the video is just a tin box - no carpet, nice vertical edge, etc. Great for the salesman demo, but YMMV!
