Power Gear Electric Jack Question

[dawop01]

I own a 2007 Fleetwood Discovery 39V. I recently had to have the driver side rear jack worked on and they had to replace the brake on that jack due to corrosion. With the brake replacement they also put a new boot that covers the brake. The new boot is revised, and completely sealed (as well as it can be with a cable tie holding it around the bottom of the motor). I looked at the old boot and the boots on the other three jacks. The the bottom corner on each of these boots is cut off in a manner that would let water drain from where it covers the brake. But, this would allow a free flow of road dirt and grime to enter into the brake area. My question is, are these boots cut this way from the factory or have they been otherwise tampered with. The jacks are mounted directly behind the tires. If anyone knows please speak up. Any help will be greatly appreciated! Thank You.
