Interesting, I have a similar coach and added more dog house insulation (Dynamat), Sumo springs, a rear track bar and have the 5 Star tune. My the raised potion of the coach's floor is room temperature, but the floor by the door feel warm after 8 hours in 100+ degree temperatures. The DW and I can carry on a conversation in normal tones, as long as, the trans in in 5th or 6th; but in lower gears above 3,500 rpm the engine does get noisy. I have no trouble hearing and talking on the CB at 60 mph (my typical cruising speed). I would check the wind barrier around the engine compartment (actually between the engine and transmission). It should block all air except for that that escapes around the holes for the wiring loom. You can always tape around the perimeter to make a better seal. Use metallic aluminum duct tape.
