on the front plate, I think ”upright” covers vertical, and “horizontal” covers orientation left to right.
Keep on rocking, the truck is turning out great.
On the left / right thing. Nope, It is common for example for a new Lexus or BMW to have the license plate mount on the drivers side of the front bumper so that it is not in the way of the lower grille. And it would seem to me that upright would be if you look at a 3D grid, let's say Upright is your Y axis, horizontal is your X axis the unnamed left / right would be on the Z axis and would require all 3 coordinates to have an actual specification of orientation and location.
Sorry while not exactly super accurate the word Engineer is actually in my job title...
I've got the uprights for the bed cut to length now. Honestly this would be an easier issue to deal with if I was working with a different water tank. And how much water do I need now?
It occurred to me that I was still designing for 2 people, 1 week between replenisment of supplies. And should all else fail, I have a hitch haul I can strap tanks to, or carry them ON the bed. It is not an absolute requirement the water cans go under the bed. I was just trying to get the weight in front of the axle.
I cut the uprights down to 12" even though I should have gone 11", so I bobbed 3" instead of 4... I might come back and cut them down 1 more inch before reinstalling.
The idea I had behind the water capacity is that I am a big guy, and NEED a daily shower, I can do a navy shower in about 2 gallons. My wife with her long hair took 4+ gallons so we were figuring 7 gal / day for just bathing which I know is a lot. I was working on teaching her how to get wet, turn water off, soap up, turn water back on and rinse off. I never got that far... Anyway, if I could be somewhere with a reasonably clean filterable water source, I could easily do with only one of the AquaTainers and a couple gallons of purified water for cooking. That should get me going, filtering should keep me showering / doing dishes and all should be good.
