I actually build something similar, here’s my thread if you want to read up on it
When I was designing mine I used TinkerCad. A 3D mock-up software. Here’s the thread to that where I discuss placements, weight distribution, etc.
I will say, I think the wand storage using tubes is great, I did the same but with that horizontal angle, it’s going to slide out. Put them up at a 30-45 degree angle at the least. Here’s mine.
It looks like you have the ladders hanging off the side, why do that when you have a ladder rack. Put it up top! You can stack it and make use much better that way. Free’s up that entire side too for mor equipment. See the ladder I have up top? I can fit 8 more if I wanted to without sacrificing my space for equipment below.
But again, take a look at both treads I attached. Great info in both of those which will help. I have a 6x12 and I still have room to add a backup 5.5 or 8 gpm and hose reel which I do plan to do in the near future
