Need much more info and actual weights in order to provide useful opinions, but the final decision is the OP's
What is the TV's :
- GVWR
- front GAWR
- rear GAWR
- Actual weights of each axle, fully loaded ready to go RV'ing
- What does your TV instruction manual say about WD'ing...back to original height or weighting in reference to non-WD, etc
What is the Trailer's :
- GVWR
- actual weight
- tongue weight...okay to use the brochure listed, but have to use that in reference to the brochure trailer weight...this will be a percentage of the dry trailer weight. That will provide the ball park tongue weight when fully loaded, ready to go
What is the HD hitch system :
- type or brand and model
- Spring bar or truniun bar rating
The OP is going to go around in circles touching, adjusting, etc all of the various dials/knobs without the above info and am wondering if the OP knows the goal in all of these adjustments...to get the TV to what the manual recommends after WD'ing...that the trailer tongue weight should be around 12% of the trailer's actual weight...that the trailer tongue should be level or pointed slightly down...
