When I first started Rving over 30 years ago, there was no internet, and info was not so easy to get. So I had some seat of the pants lessons, that almost soiled said pants. In my experience most trouble can be avoided by keeping the speed WAYYYYY down. No highways. and under 30 MPH!! Sway for me started at about 40-45 MPH, and is scary beyond words.
So I would advise getting a proper hitch setup, or limping it home on side roads. Your 2 hour trip should grow to 4 hours.... A REAL word of caution. When I had my sway event, it felt fine, up to the point that it was NOT. There was no warning at all. The trailer brake controller saved my bacon.... YOU NEED one of those!
