I haven't used a WDH until this week and got one whith our new 29l and in the last 4 days have pullled about 2000 miles and will never go with out one again it makes the towing so much nicer smoothing out all but the most severe bumps.
The WD hitch may not solve your scraping problem, as noted above, but it will make the ride more even. It also evens out the wear and tear on your trailer tires. If the TT is hitch-down while towing it puts more pressure on the front TT tires, thus wearing them out faster than the rear. The WD hitch will level that out for you, in addition to the other benefits.
