Building a 50A RV extension cord can be a bit tricky, mostly because the "receptacle" part is not easy to find.

Like I said, not easy to find. Go out to Home Depot, and search for one. Not there. They exist, but you have to look for it.
Nine in stock here for a population of 30,000 in the entire county. They just made it a little hard to look them up.
14-50R at Home Depot My coach only has 30 amp breakers in it so you can make a good case that it doesn't require 6 awg wire. In fact, it has been connected to 8 awg wire for the vast majority of it's 8 years I have owned it with no trouble. Sometimes when camping it is hooked up to a single 120V 15amp circuit using 14 gauge wire if that is all that is available. I just have to know what power is available and manage the load accordingly.
Now if your coach really can draw all fifty amps and you only use 10 gauge wire for the extension you might start a fire but it would be extremely unlikely.
You should watch the voltage from a barn outlet at first to be sure that the wiring is adequate for the power that you a pulling, especially if you don't have automatic low voltage shutoff.
I recently ordered an 8 awg custom length cord from these guys. I haven't used it yet but have no doubt that it is adequate and it sure is easier to handle than a 6 awg cord.
