rjstractor, I have to thank you.
I was just verifying about the gasoline, etc.... and found a very interesting reference. It looks like it's likely from a dependable source....
Understanding MH WeightsIt sees that i was way wrong about these ratings.
So when there is a published CCC, that not only considers full fuel, but also considers full LP, full potable water, and includes and allowance of 154# per sleeping position
So.... it looks like I probably can add a lot of weight back in for the water and fuel, and I don't have to subtract out the family!
Since the manufacturers aren't good at listing the CCC and the number of sleeping positions, etc... I still really can't get a handle on a way to compare these units, but you helped me figure out a bing chunk of the question!
Thanks
