You mentioned the cab floor area getting hot?
Even though our 2005 24 foot Itasca has heat shields installed between the V10's exhaust pipes and the underside of the cab floor (installed by Winnebago I guess?) to reduce cab floor heat, we have discovered a real "cool" way to use the cab air conditioning for maximum feet comfort and body comfort.
We always use the air conditioning on the "MIX" cab fan vent setting. This closes the A/C vents aiming directly out at our body (which is sometimes uncomfortable with high A/C settings) and aims all cool air out both the windshield defrost vents and floor vents. Works like a champ - you get cool air bathing your feet and cool air coming into the cab up near the ceiling and then gently falling down all over you with no chilling air blasts hitting you anywhere.
We have taken 8 week and 10 week trips in our Itasca to the Eastern U.S. and back from CA. The 10 week trip was in July/August in the Southern U.S.. We learned about hot and humid on this trip - but had all the sights and campgrounds mostly to ourselves as the locals of course wisely don't go out this time of the year unless it's as high up as they can get in the Blue Ridge mountains! We drycamped one night in a Walmart parking lot and had to run the genny and A/C almost all night to get a wink of sleep.
We had a highway flat tire and shattered our front cabover window on the 10 week trip. We found out that you CAN travel a few miles on only one tire of one of the motorhome's rear dual sets - but you do it REAL SLOW because of the tremenduous overload on the remaining tire. What we went through with the shattered cabover glass in order to make it all the way back to CA from Mississippi I NEVER want to repeat. The 8 week trip went much better with no disasters - you never know wants going to happen on any one trip!
We just switched to Coach-Net emergency road service for our RV because of a bad experience we recently had with AAA - which I had been with for over 25 years. We can get 9-10 MPG on the level with no headwinds if we cruize at only 55-57 MPH.
Congrats on your long and enjoyable excursion! I always read your posts because we have similar motorhomes - except yours is more compact for even better access to all the wonderful little NFS campgrounds all over the West!
