Ceiling ripple in rear

[mmeburges1]

I have noticed on the '72 Trade Wind I purchased that the ceiling has some ripples/bulges in the inner skin just in front of the bathroom door about a one foot section where the ceiling starts the transition into the curved rear. As the skin starts to make the curve it has bulges in the area where the center ceiling skin meets the wall skin next to the trim pieces that hides the seams on both sides. The bulges I'm talking about are like you would get if you tried to make a complex curve out of a flat piece of sheet metal. Is this common or might I have a problem that has caused this.

Thanks,
Mike

I believe your describing a situation where the top of the bulkheads want to punch through the ceiling vinylclad metal.

If that is the case, then the basic cause is two fold.

The first is usually caused by towing many miles with improper running gear balance.

The second is caused by axles that have gone bad.

In the first case, severe vibration can cause the shell to flex enough, especially at the wheel area, to cause the top of the bulkheads to punch holes in the ceiling.

In the second case, bad axles will allow the trailer to "bottom out" when hitting bumps, again causing extreme shock to the center as well as the rear end of the trailer.

I would suggest that you also check your trailer for rear end separation, AND, damage to the frame and/or axle mounting plates.

To learn how to check your axles, you can go to our web site, inlandrv.com

Click on articles, then click on the dura-torque axle article.

Perhaps that will answer your questions.
