I'm installing a 50 amp RV outlet on a power panel. The charts indicate you can use #8 for 50 amp but my co-worker is saying I need #6. The length of wire is less than 5 feet. Comments please.

If the lugs you're connecting to are rated for 75 degrees #8 is good for 50 amps I think, don't have my book in front of me.....
and as 480 asked what type of wire?
 
I doubt that the RV outlet has 75° C terminals so your #8 is NG unless you want to pigtail the #8's to #6's at the outlet.
 
In 20 years I have never seen this flagged. Millions of range and RV outlets are done this way, etc.

It's fine if the terminals are rated for 75° C. If not then for 20 years someone has been doing it wrong. :)
