How many of us are there? Owners of Dodge based RV's?

Godd advice Griff, I'll look at that soon as I'm ready to take the beast back out on the road. My wife has me working cosmetics at the moment. Did discover one interesting thing when i took the dog house out to look for motor size. There is a HOLE in te transmission housing on the top. It's cut, so I'm guessing it's supposed to be there, I'm just wondering if it shouldn't have a plug in it? I can look down intot eh innards of the transmission. Not sure I should be able to do that.
