One thing I like about the Carrier low profiles is the "sling Ring" on the fan that trys to get energy recovery by re-evaporating the condensate that usually runs down and makes a puddle. You pay for the energy to condense the water out of the air, might as we'll use it to help by splashing on your hot side coils.- Definitely get the slow speed fan- Spring for the lower amp draw option if availableI have Two Colemans that I have yet needed to run both on high at the same time. I believe they are the lower amp draw, I'll have to check the model number with the next camping world flier.My $.02Let us know what you pick
