Livestock cart/ wagon plans

I am seeking sources for livestock drawn cart/ wagon plans. Currently most
needed are plans for vehicles light enough to be drawn by a single jackass or
quarter horse. Plans for vehicles using up to four horses also welcome.

Sources for creating my own harness for donkey, horse and ox also very welcome.
I have no desire to purchase harness ready made. If I make my own, then I know
the quality of materials used and can make the harness truly fit the animals
being used.

I would prefer to use automotive wheels and tires instead of wooden wheels with
iron/ steel rims. Two wheel buckboard styles with cargo capacity to haul wood
or produce, load weight 100# to 1000#, to local homes within five miles.
