You can do it yourself Rob. There are a few adjustments and a few goals but all are within the realm of most any mechanically inclined person. I would rather learn how and do it myself than trust an RV mechanic. It is nice to be able to make an adjustment in the future without having to go back to a dealer plus I think you'll appreciate the cleverness of this gadget.
Hitch head angle, height of ball, tension on spring bars, and bendiness of spring bars are all variables. Goals are spring bars parallel to road, trailer level, and even compression of both truck axles under the load.
I will highly recommend some of the RV sites for setting up your WD hitch since they seem to explain things in a simple manner so even someone like me can understand.
The WD hitches are standard and not truck specific, but the receiver that bolts to your truck can be more application specific.
I own a Robyn brand WD hitch system with 1000 lb spring bars, I really appreciate the fabrication, cost, powder coating, and weld quality of this brand. I purchased it from the local RV dealer who sells the nice Arctic Fox line of RVs.
Summit racing sells Curt brand too. There is some healthy competition out there for companies like Reese who have highly priced their hitches for a long time.
Whatcha towin Rob?
