If it has a side radiator vs rear radiator, that will probably make more difference in cooling. The rear radiator units seem to get dirtier faster causing heating problems. The side radiator units give better access to the engine from the rear for some service issues. My coach has no bedroom slide and the bed lifts up giving great access to the top of the engine as well. The coaches I have looked at very with how much access they allow, and it seems like if there is a bedroom slide they allow less. Not having a slide sure cuts down on usable space in the bedroom.
