Doesn’t sound right to me. I’ve had four fifth wheels over the last 35 years ranging from 27’ to 37’ and have never had a fishtail once. Have never been affected by semi’s either. Get a long STRAIGHT two by four and lay it across both tires on one side and then do the same on the other side. The two by four should touch each tire on both the leading and trailing edges. If there is a gap then you have an alignment issue. Check your spring hangers and see if they are bent or if any suspension bolts are loose.
How much of a fishtail are you getting? Are you nervous when towing and perhaps over correcting for minute movements by gripping the steering wheel to tightly?
You should be able to drive 65 mph and not even notice the trailer is behind you.
