Ive got a 2006 f 350 drw 2wheel drive and my camper is a 02 lance 1130
My f 350 came with sway bars but I upgraded to the helwig front and rear.... made a heck of a difference. The Helwig bars are much larger diameter and was an easy install.
I thought the lower stable loads were too expensive, and after some research on this site I am trying out the DIY method of using the splitting wedges (orange plastic wedges) and they work great on the lower helper springs. I also use the upper overload spring blocks similar to the torklift upper stable loads. They also work fine. The truck handles MUCH better now and I recently drove the road from Willits CA to Ft Bragg CA, (very curvy steep hilly road) Drove and handled great. I know our trucks and campers are different, very different but the idea is similar and the sway bars should work great for you also.
The Stabile loads just seem to be more money than I want to spend at this point, when the wedges are working fine.
** The road from Willits to ft Bragg, could roughly be compared to the dive to Mt Lemon near Tucson, Its been many many years since I drove that road but as I remember it that could be a rough idea, another area in AZ would maybe be near Globe AZ hilly and curvy lots of sharp curves.
