Vanimal Thanks for the comments! You are 100% right that the scale on the renderings are off. I currently have two models going one that is on my previously modeled Van Body (the scale of this one is off) for the overall design look, and then a more dimensionally accurate bumper model without the Van body. I modeled the Van body before I had a van back in early 2020 using the Ford Body Builder Layout Book. It was pretty rough since it was just for visualization, not for true scale, so now my one model is more just for the overall lines and shapes rather than a true working model. I know that for most the ability to open one door without opening both swing outs is ideal but due to my rear drawer design, there isn't a whole lot of benefit to having that as an option for me so I'll probably just squeeze the tire and box as close to the center as I can. I would be curious to see pictures of your bumper if possible as it sounds like you have the integrated hitch pretty dialed.
Here are a few additional model views of the bumper that are more accurately scaled, but still not 100%.
Also while I was making some changes and additions I thought I would see what an additional storage rack above the tire would look like as
Twoxentrix had suggested. If I did anything like this I would make it modular, so I could add or remove it as needed.
The next steps for me are to get some cardboard and start taking some of these ideas out to the van and see what problems exist in the real world with this design. So far the biggest problem I am seeing is the wrap-around design and how that will interact with the van body. If the body in this area was like a truck bedside (which is a single layer of sheet metal) I would have no problem with cutting it away to allow for the bumper to cap under it. Unfortunately, this area is double-walled sheet metal that connects to the rest of the interior van structure so this might cause some problems. We will see if I can come up with a solid solution for this once I get into the cardboard stage of things.
