I take it this is the draw bar(trailer hitch)on the back of your truck and not a tractor draw bar. I have used them flipped a lots of times with different trucks to get the trailer higher and also to lower the trailer tongue. It should make no difference as far as the strength of the draw bar it is made strong to pull the weight and they do have the max. weight wrote on them most of the time. A lot of people don't really understand that really the weight on the draw bar(trailer hitch) should not be very heavy the load should be mostly on the axles and tires of the trailer. No more than 10% to 15% of total trailer weight should be on the tongue.![]()
