Having seen EV pickup trucks reviews in which they failed to complete a course within their advertised ranges while towing travel trailers.. The course was a standard highway. I can only imagine being stranded some where off road waiting for the solar panels to recharge my batteries. Of course...
Have a mechanic inspect the bushing, it takes a few minutes. The condition inside can indicated if the bushing is shot. Is this the first time you inspected the Gladiator under carriage?
