Here's a link to the brochure for your coach. It says your gross weight is 47,600. Your cargo limit is the difference between what you weigh empty and that number, or the remaining cargo limit is the difference between what you weigh now and that number. I'm not sure I've seen "empty" weights posted very often. What matters is what the scales say you weigh, and what weight you have on each of your axles.
We've weighed our coach quite a few times. When we were setting up the tag loading, we made several runs thru the I-84 truck scale east of town and tweaked it until we were happy. Since then, in Idaho and Oregon at least, we've found quite a few scales along the highway operated by the respective transportation departments that we've been able to pass thru and note the weights on each of the axles. Those scales are normally un-manned, but they leave them on with a pole mounted display that lets the public use them.
