I think it is pretty much up to the GM. I usually play it as a cart can carry about 500lbs, every 10lbs extra gives a 5% chance per hour of travel of it breaking. A wagon carries 1000lbs, with each 20lbs extra giving a 5% chance per hour of breaking down. The players can buy more sturdily built ones for an increased cost. Also, the condition of the road can play a role. If traveling on a well-maintained road I decrease the chance of breaking down, and increase the chance if travelling on really bad or non-existant trails. In any case I don't roll for break-down as long as they are under the maximum weight.
