you like Torklift StableLoads? / Upper, lower or BOTH?

See my truck and camper in signature.
Since my truck has the camper package it already has the sway bar. My payload is 4226 lbs and wet my camper runs 3600-3800 lbs (weighed at CATScale).
I think my combination handles wonderfully and I have no issues with it at all.
To each his own as to what works for them as there are many ways to skin the cat.
