WDH question...

I hooked up the TM to the Tundra for the first time last week. With no WDH, it dropped the rear about 1.25 inches. Just pulling it about 10 miles to the house. It pulled fine and rode really nice. The front end did not feel light at all.

Hooked it up later and used the WDH load bars this time and the ride over irregular surface (dips, bumps, etc) is not real comfortable. I think the WDH is using either 1200 or 1500 lb bars. I was on link #3. Raised the back about 3/4"

Question is, if i used lighter weight rated bars, would the ride improve? And I'd still get some leveling.
