Howdy Pronghorn1! My wife has some ancestors from up that way, and I have a neighbor 90+ who moved from there to CC in the war. Been meaning to get that way for a stop on one of our next trips.
I know you'll enjoy that trailer, make the local certified scale your friend. I may be repeating what you've already gone through. Grab one of your friends as a helper makes setting hitch rigging easy. Dealers are okay, but the confidence you'll gain will make any on-road changes that much easier by having gone through the details yourself:
You'll want the TV empty (driver w/full fuel only + normal junk), and trailer (preferably) with full propane and fresh water. Nothing else.
On another day, take it across again with everything loaded for your trip.
You may find the below helpful, but what is mainly wanted is all axle weights empty, first, and loaded, second time. Tongue weight is also needed (whether derived or actually weighed)
You might like this chart to use.
(Per Ron Gratz over at rv.net)
TT attached and Weight Distribution Activated
Let Front Axle Load be "FA1"
Let Rear Axle Load be "RA1"
Let TT Axles Load be "TT1"
Then, while in same position on scales, take
TT attached and Weight Distribution Not Activated
(in truth, it may be good to circle around so scale re-sets)
Let Front Axle Load be "FA2"
Let Rear Axle Load be "RA2"
Let TT Axles Load be "TT2"
Then, drive off scales and drop TT.
Return to scales and take
-- TT Not Attached
Let Front Axle Load be "FA3"
Let Rear Axle Load be "RA3"
From the above values, you can calculate:
TV weight = FA3 + RA3
Gross Combined Weight = (FA1 + RA1 + TT1)
- should also be equal to (FA2 + RA2 + TT2) if scale weights are correct
TT Weight = Gross Combined Weight - TV Weight
Tongue Weight = (FA2 + RA2) - (FA3 + RA3)
Load Transferred to TT Axles
when WD System in Activated = TT1 - TT2
With some pictures of the hitch rigging take the combined info over to the thread:
The peanut gallery around has some pretty good eyes, and, with both empty and loaded axle numbers plus TW, they'll help you really nail it.
(And, for what it's worth, I'd only have a Hensley Arrow or Pro Pride; second place goes to a REESE "Dual Cam". You can find plenty of arguments about them all, but that's my take on it. Ck Craigslist).
Believe this was from BryanL:
Adjust the hitch ball height to 'level' the trailer
Adjust the weight distributing bars to 'level' the tow vehicle
Adjust the hitch head angle to 'level' the bars.
