A very good idea is to not make "Definitive" statements.
The proper statement: ON SOME A chassis, they are different
ON OTHERS (mine for example) they are identical.
Oh, I know they look different....But they are not.
IN fact.. When a rear tire blew early on we moved the front tire to the rear to better match wear patterns. Just turned the rim around (Since it was the outer that popped) and bolted it on... That was like 30,000 miles ago.
So the joke is 3 groups of men were ask "Boxers or Briefs?"
The youngesters answered one way
The middle age another
And the oldesters... Gave the answer I am giving to the Original Poster's qustion: DEPENDS
It depends on the make and model of your RV,, Some are, Some are not.
