The two C's we've had didn't come with ladders but we got both used, so who knows. I can say there was no evidence of one, like brackets or worn spots. We carried an aluminum stepladder, of the height corresponding to the bunk. We had to go to Ace Hardware to get a 5-footer. 4-ft and 6-ft are the common smaller sizes. I think most newer C's would do with 4-ft. I thought of customizing a wooden one, eliminating the back legs, carpeting it, etc. But the folding aluminum one, even though short, helped with a few outdoor chores. I could NOT get by with a bunk ladder like the ones with rungs like an extension ladder. We felt we'd reached an age that shouldn't be climbing in/out in the dark. Replaced our 24-ft C with a 31 that has bed down.
