Hello, This may be a bit "off course"... we have a vintage trailer/and tow vehicle. But we have a Reese sway bar for our 1963
Bambi (likely quite a bit lighter than yours). Hubby drove it for a while without one, felt it was okay....but then we got the sway bar and he is firm at this point. He won't ever tow anything without some kind of sway system! Recently we were on a trip to Baja and driving down Hwy 101 we had a farmer towing a big long implement trailer pull right in front of us, (we think he forgot he was towing an empty trailer)... we had to swerve dramatically and our little sway bar took care of everything. Without it, we might have been in trouble. I would pay for safety items first!
