Cab heat
How can I disperse the engine heat when I stop from flowing into the coach area. I put roof exhaust fan on and start air asap. It still takes some time for this heat to go. Curtains don't do the trick...

To the OP: For stopping to camp and not wanting so much of the heat from the huge engine/transmission mass adding it's heat into the coach interior ... I open the hood for a couple of hours and also immediately block off the cab area from the coach area. Winnebago supplied stock curtains for blocking off the cab from the coach. We also block off the cab for more efficient winter heating of the coach area and more efficient summer cooling of the coach area from the roof A/C when camped.
To TyroneandGladys: From you photo .... I'm scratching my head as to what are the physics going on such that the piece rubber/plastic/metal(?) dam hanging down behind the front bumper can keep the engine area cooler and hence keep the cab floor cooler?
It seems to me that it woudd kindof do the opposite .... BLOCK outside front air flow from going both up into the engine and underneath the coach flooring to help cool both when going down the road - plus maybe create a bit more overall frontal air resistance so as to reduce gas mileage.
For some reason, our Ford E450 Itasca Class C came from Winnebago with straight-forward simple metal heat shields between the exhaust piping under the cab floor and the cab floor. Our cab flooring does not get uncomfortably hot going down the road. In hot weather we also sometimes run the cab ventilation system in MIX mode with the cab A/C fan set on one of it's two highest speeds. In MIX mode there is no air conditioned cold air coming out of the cab vents blasting chest-high right into the driver and passenger. All of the cold air comes only out of the windshield defrost outlets and the FLOOR outlets! This keeps the cab flooring extra cool, plus also keeps cold air out of your face. The chilled air coming out of the defrost vents rolls up along the windshield and gently sinks down around the driver and passenger such that we feel no chilling air blasting our faces, chests, or arms. It makes for a great overall comfortable temperature in the cab with no hot floor (... ours doesn't get very warm anyway due to the shields) and no cold air blasting directly on you. (I discovered this MIX dash ventilation setting air conditioning trick completely by accident several years after owning our Ford based Class C ... as I assumed that only HEATED AIR would come out of the windshield defrost vents. With the temperature knob in the blue region cold air comes out instead - along with cold air coming out onto your feet!)
