To rough in the vehicle lashup is to measure wheelwell fender height. Crank the bars so that this number is the same once hitched at the Steer Axle.
Proceed to a certified scale to dial in. One wants full fuel in the TV and sand bags or other to simulate passenger and gear load. TT needs full fresh water and propane. Approximate the usual gear and supply load.
Three passes across scale. Once with hitch roughed in as above. Second time is across scale with WD fully slack. Third is to drop TT and go across scale to get the TV weight. With these three scale tickets one can determine needed FALR (front axle load restoration).
Some hitch adjustment may be needed. Be painstaking as future adjustments will be small if lash up is done well at first.
It may be that the rear of the TV is down slightly even after FALR. Not important, generally. What IS important is that the TT is level.
With a level TT and close FALR then one might decide suspension mods could be tried. But one has -- by the above -- the necessary numbers to help in that evaluation. There is no way around setting a numerical baseline to make decent decisions, IMO.
The truck payload may change, etc. Some spring mods are not so great when using a WDH. But that is ways off
Find a CAT Scale after loading the vehicles appropriately and doing a rough-in via fender measurements at home. Adjust the hitch according to directions for FALR. Re-take front and rear fender well measurements.
Those numbers of measurement and weight are what to post. Pics of the rig showing the hitch and part of the vehicles, and then of the combined rig as a whole. Find some nice level ground.

Crank more WD...
Ted,
The rig doesn't look level to me, both AS & TV.
Have you taken measurements or been to the scales?
Towing priority.
LT tires on the TV. D or E rated.
Class V or IV hitch/receiver, set-uo properly with WD and sway.
Tight suspension..... shocks, ball joints, bushings, steering etc.
Check the front and rear TV axle ratings,(usually on the driver door jamb sticker), to determine payload limits.
IMHO...leave the add-on Roadmaster,(helper springs) and air-bags,(elevators) on the shelf. They really don't add payload or aid in towing.

So I have LT truck tires E rated on the TV, Class V hitch, Propride, and the entire front end of the TV was inspected, everything was tight, steering box replaced.
I will go across scales, my thought is the Propride is not adjusted properly? I can tighten the WD bars, correct?
Time to take it to the scales...fortunately they are close by.

Yes, looks like the jacks/bars need to be tightened up to me. The ProPride bars will get a lot of curve in them when loaded properly.

Ted,
POI....I started out using 1400lb bars with the Hensley, changed to 1000lb following others suggestions of the need for a softer ride & less stress on the AS.
Fully loaded I can transfer 660lbs forward to the steering axle and 160 back to the AS axles.
They do bend....

What Suspension Upgrades do I REALLY Need?
I did some reading around on the EX. The V and B code springs would be on my list. And I'd ask owners such as perry114 on this forum for their opinions AFTER I'd established FALR and re-measured the TV if the TT measures level.
The EX has about the worst steering, handling and braking of any TV of the past twenty years. There is plenty to diagnose and adjust and maybe modify. Put the TT tires at full pressure, adjust TV pressure to spec according to door placard and with 100% FALR one has a place to start. Alignment on both vehicles, brake drag, and bearing preset. Take time and verify these. Get some road time. If any changes are warranted try adjusting hitch, TV tire pressure, etc, first.
