Any idea what a stripped tub weighs?

I'm going to have to move my tub around to various places over the next few months, so I considered making a wood cart. Then I noticed Harbor Freight had these inexpensive trailers ($300), and in particular one that folds up. So It got me thinking that I could use it as a cart to move the tub around and save on flatbed charges, and maybe later use it as a vertical top caddy in the folded position. They also sell a trailer dolly for $50. I mean at the very least it would make getting the tub on and off of a flatbed that much easier and is probably sellable on craigslist for almost what you pay for it even if it wasn't really enough to trailer the tub around.

The trailer is rated at 1100 lbs and I know the tub weighs less than that, but how much less does a stripped, doorless, gateless, topless tub weigh?
