Frank, your TM is very similar to ours, a 2001 2720SD. Here is our first trip experience for loading:

I never weighed things after, but we've never packed so heavily since. We now buy our food local to our camp site. If we need the fresh water tank filled, we fill it up near our destination. You will note that it cannot be filled when closed, but some have modified their trailers so that the fresh water tank can be filled from below when closed. I gather it's an easy mod.
We also bought a washer and spinner from the laundry alternative so we don't have to pack so many clothes. Other than that, it's just trying to convince my wife that we "don't need it". I'm fortunate though, having the Tahoe we can generally take whatever she wants so I don't worry too much.
