Tongue box on single bar tongue

My wife and I are the proud new owners of B Bodemer's woodie tear.
I had started a Benroy build about a year ago and realized that I didn't have enough time to dedicate to the build. This tear is beautiful and superbly constructed. And the best part is we can go camping immediately!
Anyway, we spent last Saturday loading it with our camping gear and going over what we might want to do to personalize it.
One of the first things I would like to do is add a tongue box for the jacks, canopy and miscellaneous tools. Our tow vehicle has a 150lb tongue weight limit so a plastic one may be the best option.
My concern is attaching it. The tongue is a single bar, not an A frame. I don't want to drill any attachments into the trailer.
Anybody have some ideas?
