I had what is called ,a trailer toad between the stacker and the hitch. Takes all of the tongue weight off of the hitch.. But when I was backing up somehow the weld let loose.. Newell said the hitch was rated at 18000 pounds.. The stacker is less than that and total tongue weight at the time this happened might have been 3-4 hundred pounds tops..
For what is worth ..looks like this has been cracked for a while as rust is evident, along with a cold weld with little penetration.. Not much comfort I know...
Another one of those things I worry about.....I'll be inspecting mine shortly.
