Be careful how far you take that assumption. While the trailer does give you some down-force at the trailer hitch, and some lateral stability based on which side it might currently be Jack-Knifing ...

The end of the trailer tongue has a circular fitting in the square steel rod. It can rotate along this circular piece and NOT transfer rotational forces to the 'bot.

In other words, when/if the trailer ever tips completely over, the 'bot will not feel the rotational tipping forces at all.

[edit] Take a close look at the trailer drawing (GE-09000), page 3. The Trailer Tongue (Item #5, GE-09009), and the Hitch Swivel (Item #19, GE-09036)

[edit2] Then take a CLOSER look (as I apparently did NOT), and notice Item #50 clearly pinning that Hitch Swivel. ...and then disregard my mis-informed advice above. Sigh. I'm 0 for 2 this weekend. Maybe I'll start lurking instead of posting.

The round stub is pinned to the square tube in the Trailer Hitch. They do not rotate relative to each other.

That's a last minute (12/29) design change?
