Just finnished installing the Kodiak Discs on my Road Runner 4800. Very simple and good instructions(pictures) seeing as I was converting from drums to discs. The only issues I had were dealing with corrosion issues on the old drums. I also had to install a new surge actuator, as the old one I had was not compatible with disc brakes. Total time to tear down and re-assemble and back on the road about 5 hrs.
I must say significantly less parts and farting around with the discs vs the drums at least from a strip and assembly point of view. I guess we will see how it all plays out in the long run.
Boats run on Gas, not Thanks!
