to a point but really have the truck be rigid too. pushing on the back of the trailer lightens tow vehicle, really what it boils down to is you are almost at the weight a 1500 would have no problem with and 3/4 has the weight and suspension to mitigate the movements of the trailer even if its a bit more off balance than normal.(what they are made for) this is why I'm saying something is wrong. adjustments or shocks would be what I would be looking at plenty of trucks have no bars, things over 350s because the suspension is stiffer and you don't need it
