Yeah, looks like the upgrade kit is a pretty easy install :

I've only had my camper a few months, but now that I see my original 3-speed can be upgraded to the 6600 with a kit, this looks like the way to go. Seems to cost ~$200 when I do a quick Google search.
I went with the 14 speed upgrade kit also, was easy install. One thing that I did not care for and my wife hated was the auto vent opening and closing. Easy fix back to manual, I just disconnected the wiring. Make sure you program the remote also, I did not do this until recently. Lower speeds run very quiet.
