Greetings from an ex- Michignader or is it Michiganian... Of course some say Trolls.

I really like your analysis and design. If I had tools like that, I'd spend days playing 'what if' because, but I'd never get around to building anything. But that's me.

I don't know about your space constraints etc., but did you try an analysis with some type of reinforcements over the top of the frame and bumper? Twisting of the bumper by the weight and bouncing of the storage box on the fabricated bolt-on supports would put a lot of stress on the upper welds. The commercial reinforcements bolted to the frame would help counteract the twisting if they were thick enough and, of course, help hold the bumper if/when the welds failed.

I know what you mean...I tend to way over-analyze these things! (my brother lives in Arizona!)

If you look at the previous bumper stress pics (blue) you can see that adding the added braces in the lower two pictures take the stress off of the welds. Kinda hard to see in those pictures. I copied that off of a commercial product here: https://www.mount-n-lock.com/product...e-safetystruts

So. That helps prevent the 'twisting' on the welds. I understand that the 3 supports I added would apply those stresses if the weight is solely on them. My intent is to have the back part of the tote to rest on the bumper. So the weight would be distributed between the 3 support and the bumper (with the braces keeping the weight off the welds).

Here are a couple stress pictures with 100# on each support and 200# on the bumper. Understand that this is a static load, but it is a good indicator of actual performance.

In the picture with the blue bumper, the weight is applied to the outer edge of the supports. This would not happen as explained, the weight would be even across the braces, but this shows the stress the individual support can handle. The picture shows an exaggerated theoretical distortion. Where is is RED, it has moved 0.07312" from its original position. The further down the color bar on the left, the less movement.

The yellow picture shows where the stress (green) is on the bumper braces (or struts).

So, this is with 500# total. I won't be anywhere near that, so I think this will work.

The only wild card is the dynamics of driving down the road with weight in there, but I feel confident that it would be fine....

Thanks for the added info. Somehow I knew (but didn't want to assume ) you had analyzed the torque on the bumper in addition to the weight.

I'll assume that folks are "weighing in" the additional weight these attached items add to the total amount of towed weight of your vehicle.

I say this only because the bafoon neighbor of mine accross the street placed a ton of stuff on his TT; all on the tongue of the campers trailer. The nose made the camper sag the front about 3 inches when he hitched it up to his truck. No doubt he was close, if not exceeding his maximum tongue weight.

I can't speak for others, but in the spirit of over analyzing, I will be measuring tongue weight before and after. In my case, it could make the tongue lighter as the weight is on the back. I will probably load up the container with more than I intend to carry and test from there. I will probably use the bathroom scale method which should be close enough for my purposes....

Here are the brackets I fabricated....they are 7 gauge steel. Now that I see them in place, 11 gauge would probably be fine.

All I need now is to mount the container (after I buy it!)
