After alot of thought I decided to sell my FunFinder. Don't use it enough to justify expense.
Replaced bath fan with reversible Vortex II w/cover.
Replaced bedroom fan with Turbo Cool evap cooler/2 direction vent fan. Runs on 12v.
130 watt solar panel, Bluebird control and 2 interstate 6v golf cart batteries.
Upgrade water pump, better flow and quieter.
All lights have LEDs.
Maxxis tires installed 6/2015
Everything works and no problems.
