Anything that moves must be flexible or it will break. Airplanes for instance. Ever sit at the window seat and watch the wings move up and down? That's not because they are built cheaply. It's because if they didn't flex, they would surely break. Same with automobiles. They actually flex and they are designed and built to do just that. It's the reason the frames are bolted and riveted together instead of welded. Yes there is welding in places but the basic frame is built to be flexible. Even in unibody cars they are flexible. If you build the entire trailer to be stiff, it will break in places and they won't be in good places. There are plenty of places where glue has it's good points and I use glue a lot in my builds. But the trailer as a whole should be able to flex a bit. Just my thoughts on the subject. Larry, I appreciate those thoughts and wondered similarly. However, I can feel more flex when rocking my little camper on a corner from the ground as compared to my pickup truck. Might have something to do with it being NAILED together rather than bolted and spot welded. Would love to hear from a sructural or automotive engineer on the science details. For instance, how do modern aluminum trailer body frames hold up In comparison to stick frames? Having whined enough about the historical engineering shortfalls of original productions, I gotta say I appreciate how soild these little boxes really are, considering they are just some scrawny sticks and plywood litterally nailed together. I think I'm mostly impressed with holding power of nails, given the amount of vibration applied when momoving down the road. |

The biggest problem with gluing things is if you have to take something apart later it's a real B**ch. I like screws myself.
