Cool !! I like your spirit of adventure !

A couple of simple specifications.
1. Start with AS and tow vehicle on dead level ground
2. Check level of AS: place level on inside of floor, and also measure from the ground up to a fixed point on the AS such as the lower" rub band" at the front and rear of the trailer. The distance should be equal.
3. Check the owners manual for the recommended "Ball Height" when connected to the tow vehicle.
4. When properly adjusted, the torsion bars should be parallel to the frame of the AS.
5. The tow vehicle should not drop more than 1.5 inches when hitched to the AS. 1 inch is really ideal.
6. Make certain that the torsion bars are rated for your trailer weight.
7. To make the torsion bars work properly, and support their rated load, it may be necessary to tilt the ball back toward the AS.

Keep in mind, that setting up the hitch and torsion bars properly is somewhat trial and error. There are sever combinations of adjustments that will create the perfect towing set-up. Changing one adjustment affect other adjustments.

When finished, the next trip you take will tell if the set up is correct. I actually made several adjustments to create the perfect towing set up.

Hope this helps
Excellent instructions. There are exceptions though. On my one ton I must have a drop of two inches approx on rear to get the proper ride and traction for the tv. One tons are designed for payload and have traction and handling problems when empty. Putting the trailer on the hitch gives that payload and improves ride and handling. Some will disagree.

some really great advice here, thanks everyone, is there a consensus on which hitch does actually offer the best ground clearance (without spending a small fortune, as some of these can run...)

Looks pretty much like my TV hitched to the trailer. Given that, before I shift into drive I visually make sure the pin is in the hitch and locked, the chains are securely connected, the coupler is locked down, the emergency break away cable is connected, the power cord is connected and I have turn signals and rear view camera working, the sway bars are locked down and ... whoosh off I go. I accept the ground clearance is less and account for it as much as possible - 10's of thousands of miles and no issues

What is the actual ground clearance?
I have never measured.
It seems like no more than 8-10".
Seems like the clearance at the weight bars is about the same as the clearance at the trailer axles, trailer spare tire, sewer drains, truck's pumpkin and front end components.

Pivot point forward will contribute to sway because there is more length and weight behind the pivot point.

I did not see this before, but I want to comment.

In regard to resisting trailer sway (also called yaw):

The true answer is in the physics of a simple lever.

The further the fulcrum (the point of the trailer weight where it pivots over the trailer axles) is away from the force (the tow vehicle) the less force is required to move the load (the weight of the trailer). In this example the lever is the trailer frame.

Slightly nose down on my rig is about 1/4" on a 30' trailer- barely perceptible- and probably not enough more weight on the front trailer tires to notice. I see no noticeable tread wear on my 1 year old tires.
It is as close to dead level as I could possibly get it.

I have about the same ground clearance and have only dragged once, at a gas station in West Virginia I had no business trying to get in to.
Your hitch looks good to me

Re comments about trailer sway.
The longer the wheel base tongue to wheels the less the sway, is pretty common knowledge. The longer wheel base harmonic rhythm is slower than a short wheel base (simple pendulum mechanics). However the whole rig is involved in the rhythm; the truck wheel base, the location of the hitch on the truck, the stability/stiffness of the truck suspension and the tendency for the trailer to sway all come into play. So some rules help but every rig is different. I had serious trouble with my 23 Award...so did almost everyone else no matter what the TV pulling that model. Short wheel base and probably tongue configuration were likely the primary reason. I have never had a harmonic sway on the 25 AS's that I have pulled. Doesn't mean others won't. Some sort of damping is good insurance for the time you need the sway control such as in an emergency maneuver. As others have pointed out on this post some changes that seem contrary to common knowledge actually work on their rig. That's likely because the changes interrupted the natural harmonics of the rig. Start with the rules and then systematically break them if they aren't working

On my rig the lowest point on the truck is the bottom of the hitch shank at 7" and the lowest point on the trailer is the low point drains at 7".
Everything else is 8" or more- truck exhaust, pumpkin, front end components and trailer weight distribution hitch bars, spare tire and covers on holding tanks.
