Had a water heater replaced last year--Atwood 6 gal. for a 2005
Georgie Boy Pursuit. Have noticed a substantial soot build-up
on the grate and the side of the MH above the great. Would
appreciate input as to how to solve this problem and what may
be the cause. Thanks for all your replies.

Soot is an indication of incomplete combustion of the propane. Two possible causes are improperly adjusted air to fuel ratio to the burner and a partially blocked burner tube. Spiders are attracted to the scent of propane and build webs in the tube.

In the picture below, the burner tube air adjustment is in the center - the thing with the slots in it. It is easy to adjust the air by loosening the screw and moving it back and forth to open or close the slots that allow air to mix with the propane. The flame should be blue with just a little bit of yellow at the tip. Too little air results in a yellow flame. Too much air will result in a roaring sound from the flame.

I really like that drain hose set up. My WH is a flush mount and letting everything drain into the recessed area really bugs me. I'm going to copy this one!

I like CloudDrivers' advice. If that doesn't work, I had the same problem with a '95 Bounder. It turned out that I needed to replace my propane regulator at the propane tank. After that, the soot was gone.
