I recently had the chance to check over a 2009 Allegro Bus 40QRP with the Powerglide chassis. I did some serious tire kicking and inspecting and was very impressed. I've had both Freightliner and Spartan chassis in the past and was impressed with the Powerglide's attention to detail. Many of the features were very similar to my current Spartan chassis, which I am extremely pleased with.
The new Vansco multiplexed wiring system really does clean up the electrical spaghetti typical to a coach of this caliber. The shifting of weight to transfer more weight to the front axle did make a noticeable difference in stability at the rear of the coach and minimized the tail wag from winds and 18 wheeler bow wakes.
I did a review of this chassis, complete with pictures, and road test on my website at
