I finally was able to get some snow and try it out!

Promise, last update.
I implemented most of your suggesting, like adding supports diagonally on the bottom box, and changing the support on the ramp.
Thank you all for your help. It would have been a lot harder without you guys.

Thanks for all the feedback, it is exactly what I need to make it better.
After all of the comments on the stability in the long run of the 3' box I'm going to add some diagonal supports on the bottom to make sure it never moves at all. If it were only me going on the ramp I'd probably say fuck it and just not worry about it (it is really strong, I would feel safe jumping on it repeatedly), but it's not only me going on it. It's going to be friends too and I wold feel terrible if something happened.
To reiterate, the sawhorse is Extremely temporary as in tomorrow I'm making a replacement. my friend had to stabilize it until he took the picture. It is not safe at all.
One of the things I am most proud of is figuring out how to attach the ramp to the platform. It is definitely not just drywall screws.
These pictures are from the top box, and it shows 3 2x4's with 1 1/4" holes through them
This is the top of the ramp with 4 2x4's with holes drilled through them
this is the 1 1/8" dowel that goes through them to lock them together.
I really went for overkill on the strength of this. The pieces connected to the ramp have a minimum of 5 3 1/2" screws. The only thing that could be worse than the ramp collapsing would be the whole tower collapsing.
Really, thanks for all the help guys. Every piece of advice that you guys give me is one less trip to the hospital this winter

i would definitely put some diagonal boards on that bottom box. those little corner pieces have a lever arm of a few inches to stop the beams from being torqued. if you put cross beams it has the entire width of the box as the lever arm. put them in both directions. 2 x 4s are dirt cheap. it may seem sturdy now, but after you climb up it a hundred times things start to loosen and weaken. if it were me, i'd put cross members on all three boxes, cause why not.
as others have said, that saw horse better be temporary cause it isn't going to do shit. i'd also be careful about how the very top of the ramp is connected to the top box. i can't see in the picture if you have bolts or what, but if it's just some drywall screws, you might want to add some robustness to it.
craftmanship is excellent though.
i've built all sorts of crap like this, and happen to be a mechanical engineer.

|Kapn.K||We did stupid shit. Cinder block + plywood = ramp. Pile of tree limbs + plywood = ramp. 1x10's also work(have to focus a bit more on the approach). Lots of scrapes, pain, getting the wind knocked out of you only being able to mutter, "Don't touch me!" to your friends and thinking your parents are going to kill you if you broke anything. Wood, tools, and supplies cost money(limiting factor for most young people). There's always gonna be the "right" way and then there's something that might work and is within your reach. I admire that he's doing it.|

|Kapn.K||It'll work. He said the horse was temp(probably because it slid out while testing). Replace the saw horse with two 2x's from the joint to the base of the platform. That will tighten everything up. Add vertical ones from the joint to the ground if the first pair didn't do it for you. I use screws for everything but have used whatever in the past. It might get a little rickety as you use it and you just add a 2x here or there. You'd shit at the half pipes we used to build in the woods back in the '80s. They'd last maybe 6 months before someone's dick parents would destroy them. We'd hit the construction sites again and do another location. We were in 7th and 8th grade. 3 or 4 sheets of plywood on the tip of our old school ramp boards riding 2 miles, etc. No one ever even questioned us.|
