interesting. I just thought about making such a thread.
I use a Hummve as base vehicle as it has heavy duty frames and armor as I like it up front.
I made it longer step by step. The back wheels are where the cursor is, in the middle. Which is funny. Like this the back should throw sparks on every acceleration. The backwheels where installed, when the vehicle was below 8 tons. At 9 tons I could not change the wheel positions with the 8 ton rated bottle jack. I was to lazy to remove enough stuff to be able to change wheel positions and kept going.
I have the feeling the chemical set can do anything the kitchen does, so the kitchen could be removed for extra storage space.
I use trunk floors instead of aisles. In case you drop something by accident (like pressing “d” instead of “D”), it is not lost but in the trunk. Also a full trunk gives a yellow log message, so you notice that something is going on and the risk of loosing something of value is minimized. Cargo spaces would also work for walking space but I dont like the 400 movement cost. In case zombies nock at a door you want to get out or get going fast.
I had solar in a 3x4 config on the roof but they get damaged when you drive like 45° and zombies try to become a passenger. Now solar is mostly in the middle.
The cargo and fluid storage in the back frequently snaps off in tight spaces, even when only driving forward. I lost stuff in the back two times while travelling from the starting shelter to the refugee center. That was annoying.
I have the bed between fridge and kitchen as eating/drinking is done often before and after sleeping.
I like the 50 cal for a turret as it has semi auto fire.
(Not in the pictures) I installed headlights in the rear sides of the vehicle and pointed them to the side to see more at night. So i have a lighted area of four headlights. Theese headlights are in the same row, where the last internal cargo spaces are.
