I like what I read for the most part, but it is again so many small things packed together in one big yes or no proposal.

I don't think splitting into wagon kits and wagon repair kits makes much sense from a market and crafting usage point of view. Why do you want to do 2 items? Make "wagon parts" and any existing wagons are just replaced by 2 wagon parts. You need one part to repair and two to build from scratch. That way you keep it at one item and you don't create two different inventory items.

Advantages:

• A producer doesn't need to decide which kit to produce.
• A consumer can't buy the wrong kit.
• You don't run into a scenario where the value of wagon kits declines over time due to saturation.
• You can use the wagon parts for other things if you ever want to introduce different gameplay elements, just to throw out an example, a guild wagon for guild conflicts.

Also I can't shake the irony of removing pack types for the sake of simplicity and introducing a second type of wagon kit at the same time. ;)
