We like the 36 MDDS leg room on the passenger side. My wife uses the extended leg rest most of the time while traveling. You have to extend the seat back and up, but that's not a big deal.
We like the mid-door because we don't have to haul all our clothes, groceries, etc. all the way through the coach each time we load or unload it or vist the grocery store, and the awning is available in the rain.
