j4nash. I have a neighbor with a 2007 and yes that size was standard. I can't remember my std size for 2006 but it was skinny. I even got grief from my dealer about going to a size bigger.
renoman69. That's what Jayco needed to do because when I saw our 09 it was low and I was concerned about it. Of course, the dealer said "don't worry, we'll take care of that" !!
BTW. Your name rings a bell. Did or do you frequent the Trailer Life forum?
