Rv websites are a hoot when it comes to folks bragging about their hitch brand/type doesn't require a tug test or bashing other brands.
On haulers type websites everyone is in agreement only a fool doesn't do a tug test with any brand OTR professional type 5th wheel hitches.....and admit any brand can be hi pinned which can result in drops.
There isn't a hitch maker out here from the lightweight rv type hitch on up to SAF Holland.....Fontaine.....Jost/other OTR type hitch that doesn't recommend a tug test.
RV world tug test is optional because its a xxx brand hitch :R.
Haulers world tug test is usually mandatory regardless of hitch brand. Some trucking companies require it or your fired.
When I hauled I did the tug test when the hitch slammed shut....then a visual when raising the jacks and hooking air and electric up. I use the same procedure with all rv 5th wheel trailers I've owned.
