The rule of thumb I use is:
Revised Receiver Rating = (11 / (11 + EL)) * Mfg Rating
Where EL = the length of your extension in inches & Mfg Rating = the published rating for your receiver.
So assuming you would put a regular ball & mount in your 14" extension, you would derate your receiver to 44% of whatever the rating is from the manufacturer.
Or you can use this chart.
Assume your 14" extension will give a total extension of 25" when the ball/mount is added.
