    We just need Dale to come up with one of these for our T@Bs, with a hole for the hitch to stick out while towing  😁

    @Dalehelman you used the double sided tape to attache the & channel, no screws, correct?

    @lkc001 It really is.  I have a neighbor at the other end of the block that has two of them. You can find them on Amazon for around $240-$330, depending on size:

    Vehicles going in the opposite direction. Opposing vehicles doing 60 mph each equals a rock doing 120 mph.

    Sorry, but this is not right.

    The incoming vehicule will act as a rock or a solid structure and technicaly will not move.  So same force will apply and result.  If a car hit a semi trailer truck at same speed, of hit an in coming semilar vehicule that come faster (like let say twice the speed) them more energy than a rock will be transmited toward the slower and/or lighter vehicule and this last one will have supported more energy.  But not necessarly twice as stated up-here for equal opposing speed.

    Thanks for the clarification. I think.

    I think what Dalehelman was saying is that opposing velocities combine.  If a rock is moving at 60 mph and you are moving at 60 mph in the opposite direction the effect is the same as if a rock were moving at 120 mph and you were stationary.  In real life, if an opposing vehicle moving at 60 mph were to kick up a rock, the rock would probably not attain 60 mph.  However, even if the rock was kicked up and was stationary (in relation to the highway) and you were moving, the rock would have the force (f=ma) of your velocity.  Enough to chip a window on your vehicle--as I have discovered several times.

    I know excatly what is was saying, but it is not thrue.  Use to think that my self too.  As a paramedic, how work and traumas scene analyses depend on speed ans energy.  But After talking to a doc after a face to face impact between a 1990 ish jeep cherokee and a 53 ft semi at 60 miles per hour, the doc told me that my assesment of the twice thw speed was wrong got me into searching and I realized how wrong I was.

    it is physic 101.  ;)

    this will explain it way better than I can.  :)

    Another way of thinking of it is all the kinetic energy carried by vehicles or brick walls (0.0) is converted to damage when stopped, aside the karmic debt portion.  KE = 1/2 m v^2.  A vehicle doing 50m/s carries four times the energy of one doing 25m/s.  But two vehicles at 25m/s carry only twice the energy.  So yup, not the same as twice the speed.  Still twice what one car at 25m/s carries.

    My brain hurts. Are the equations always in metric? I always hated physics for that. Now, dilutions in metric, no problem for me. It's physics, not math in general. lol

    My general observation is that people who worry about things must maintain a certain worry balance. I.e., once you solve one problem another arises to take it's place.  ;-)
    Nice cover, though! Can it stay in place as the window open thus doubling as a translucent privacy screen or sun shade? It sorta' looks like it can.

    Yes Scott.  We are already onto our next worry to fill that worry void!  The new worry involves a raised, cargo platform for the van cabin to allow for a flat surface.  John is on his second trip to Home Depot.  Not done with this project.  This is going to be a real redneck solution, so, no pictures will follow.  If we like the idea, I may recruit someone with real skills to copy the prototype.

    The window cover plastic u channels are mounted directly on the lexan, so, yes, you can open the window and it acts to diffuse the light.  I much prefer my red and white striped window covers😁

    I did place a layer of this plastic between the Coroplast and the window. To prevent the possibility of scratching the window.

    @Dalehelman, the Cling Window film worked nicely.  Did you put a nut behind those screws?  Our u channel holes are not threaded.  How do you get the screws to stay put?

    I uses a thread tap to thread the hole for the thumb screw.
