Bang sound when towing travel trailer
We are towing a 30-ft travel trailer and it has just started making an occasional 'bang' sound when towing. It doesn't seem to be associated with hitting bumps (which have a different sound - 'ba-doomp ba-doomp'). It seems to always happen when we are driving in a straight line on a fairly smooth road, and usually between around 40 - 55mph. Less on the interstate than on other roads. We have been towing the camper for almost 2 years - almost 40K miles, and this 'bang' sound is new. It happens only occasionally, and we can't seem to make it happen at any particular time. It just started within the past few weeks, after the camper sat for 6 weeks without being towed. I feel like it is somehow associated with the hitch, but that's just a guess. Any insight would be greatly appreciated. Thanks!
