Just before people get carried away the tank is polly/plastic so its not what you'd describe as heavy.
1 time I rented a small fiberglass camping trailer and was pulling it behind my 1/2T Dodge Ram PU doing 65 mph on Hwy 50 in norCal when it felt like the hitch had disengaged from my PU bumper The trailer stayed behind me but was moving the rearend of the truck around some as the only thing keep the trailer attached to the PU was the 2 safety chains and we were on a downhill freeway. I was safely able to pull over w/o any incidence and found the ball I installed on the bumper was attached by a bolt upside down in the ball had loosed up over time and completely fallen out of the bumper!! Amazingly we were able to find the bolt and attach it again and move on. It had a lock washer on it but the constant pulling/pushing motion on the hitch apparently had loosened it over time. Never bought that design hitch again.

I don't see how anyone rides some of those LA Freeways without splitting rims every so often.
