Math question
So after installing my new upgraded axles and springs, my WD needed a little tweak as the TT sits a tad higher. While making the adjustment, I got to thinking... It is often advised to error on the ...

I haven't tried this yet, But if I were to take a rectangular box, and hold it out the window on the highway in different positions, then that would be a pretty good test of my thoughts. I think I know what will happen
When you start playing around with your boxes, don't forget to place one in front of your simulated travel trailer to take the place of a tow vehicle that is punching a hole through the air. Also, include a roadway that will affect the airflow around the two vehicles. There about a hundred other factors to consider if you want a really scientific evaluation. In fact, they have such a thing and it is called a wind tunnel.
I don't happen to have a wind tunnel handy, do you?
Actually I have already moved on beyond holding a box out the window... A simple test that can prove or disprove weather a box will act the same as an airplane wing,, or not. I am having a hard time with the lift theory of the box... Yes I am very familier with how an airplane wing generates lift... But most of us are not towing airplane wings.
A scaled down home test can easily prove or disprove this without a lot of expense.
What is needed is a matchbox car, or a few different bodied ones of your choice. A scaled to size TT shaped wooden block. Some wire to simulated the hitch between the two, attached by a means that will work (I can think of several), some thumbtacks stuck into the block for wheels, a fan, a protractor and a digital grain scale. A wind speed meter would be a nice to have item.
Set the hitched up model TT on the scale, with the TV on some books etc by it to simulate how it would be on the road. First perfectly level, turn the fan on for wind, than take a reading from the scale.
Then repeat the scenario with different angles on the TT. From there it is just a matter of doing simple math to scale the results up to full size. If the actual windspeed is known, then it can be a very good experiment. I don't happen to have the scale needed (mine is an old beam style), but many reloaders do have this. It is very likely that someone reading this has one.
