Update - for those considering the lower StableLoads, they do now make a stainless version, for the Superduty.
However after speaking with various people about StableLoads…. I spoke with a trusted expert, and he said he had heard of more than one situation that people with campers who were using the lower StableLoads who *broke a spring* when using the lower StableLoads.
He said they can also can sometimes make noise, so he recommended against the lower StableLoads.
He did, however, say that the upper StableLoads are a *wonderful* product, and *if* it is needed, they work very, very well.
So just passing that opinion along. I have no further info.
