I currently am volunteering for the Red Cross in Disaster Services. That's why I wanted a small trailer.
I think you were right to think about selecting a UHaul
. They were originally engineered to be used independently under conditions where taken-for-granted support services become unknown quantities that cannot be counted upon. [b]BUT there is the law of unintended consequences to be factored in as well. (notwithstanding the male attitude, for which I offer a blanket apology).
Evaporative cooling systems operate with simple motors and pumps, that can be powered economically by 12 volts DC. Like human sweat, they add moisture to hot dry conditions, and use moving air to cool. But if the air conditions are already humid; adding more moisture is counterproductive. While evaporative coolers are commonplace in Palm Springs, CA they are absent in Hot Springs, AR.
systems cool by subtracting excess humidity and using moving air to facilitate this cooling. Unfortunately, this extraction process is too power intensive for 12 volt DC systems to operate.
The factory that built UHauls selected evaporative coolers for their operational economy; not their geographic
effectiveness. This misunderstanding (probably male induced) contributed to the demise of the rental business model.
