Lake NICARAGUA is the lake with the freshwater sharks. And northern Nicaragua is the coolest part of the country and it is anything but cool especially in summer. Teguchigalpa, the capitol swelters. It is not high elevation. Jesús, told me last night Las Pe?as finally managed to cool off. It was a pizza oven when I was there a couple of weeks ago. I do not being trapped "inside" either by heat or cold. I will move. All this is the reason I have a phobia about STUFF THAT DOES NOT BREAK. Look for a controller, or cyclable battery and you might as well be looking for a nozzle deflector for a Saturn V rocket. Six years on an RV battery is not good enough I want to spend ten seconds a day and have it last 10-years. Put the rig up on a ramp and paint the tires with silicone lube once a year. Now perhaps you can better understand an upcoming post of mine about replacing the capacitors in my WhiffCo BEFORE THEY FAIL.
