And if this is the truck you haul that camper with then i would think you want comfort on long hauls.
By Z link are you talking about 2 parallel bars going forward and then a nother bar at a 45' between them, like the rear suspension of most drag racers? If that is what you are talking about i dont know how it even fit up front and strength would scare the hell out of me. Why not the topical radius arm with track bar. Its proven and works well.

The z bar design i am thinking is used on VOLVO trucks and with the design there would be no axle wrap and only one pivot point .

Jcart the heim joint was thought of too but they are noisy even if greasable but i havent totally given up on the idea yet ( of heim joint )

I would stick with poly bushing ends and not even consider heim-type joints. There's a reason oem has this type of connection (slide in bushing), not just on p'ups but semi suspensions, too. They just last longer, more durable.
Heim's shine where lots of flex is needed, off road and what not. But for an on-road air bag type deal I'd personally stick with poly bushing joints.
JMHO...

i agree hiem joints are un reliable
