Rothschilds Carts
I know the following wall of text is intimidating, but please read on and post suggestions, because im sure i didn't get everything right
IMO
Carts should be composed of wheels and hulls which are built seperately then combined.

-A wheel would be an item which fits into a back slot, hence one can carry up to 4 of the same wheel.

-A hull would be a project which is build and has wheels added after it is built.

-Each hull will have a number of wheel spots based on its design.

-Wheels break and need to be replace periodically. A cart must have all whells the same type.

-The wheels used will affect how and where the cart moves.

-The hull used will affect what and how much can be carried.

-Each Hull with have a number of slots in which either a basket or a group of items which stack into the 'back' slot may be carried

There should be multiple different wheel types. Unless specified, The wheels only travel on road and grey road safely. You can drive your cart anywhere, but if you drive it onto the wrong terrain too much the wheels will break and need to be replaced. Even shallow water will damages wheels unless otherwise specified.

-Where wheels breakdown will be Poisson distributed over how far you've gone with normal mean breakdown at 1024 meters.

- D: fragile (4/3 break frequency)

- Weavers Heavy Grass Plate Wheel

- M: 1HeavyGrassPlate, 2twine, 1branch /wheel
- A: Easily repaired in the field, the damaged wheel can be repaired as opposed to replaced
- D: fragile, slow (3/4 run speed, 4/3 break frequency)

- the hulls should vary in amount and type of materials they can carry.
The cart will not prevent you from loading too much onto it, but overburdening your cart will increase the rate at which your wheels decay.

Just these items will yield 42 different carts which we can construct

Additionally I would Like to see watergoing crafts. In order to move your craft you will need to be on it with a paddle equiped in your hands (a paddle would be a two handed item).

-kayaks and Canoes would be 1 and 2 man watergoing vessles respectively, which work like finished carts. rafts would work like floating platforms.

-In order to move a raft, canoe or kayak one will need to equip a paddle.

-As IRL kayak paddles can be used to paddle any canoes kayaks or rafts, these will be the only type of paddle make.

-Canoes and Kayaks will have slots in which filled bins or back-slot-items can be placed.

-Canoes/Kayaks/Rafts will not break down, but paddles will with use.
