I have an 2008 cyclone 4012 bought new in April 2008. So many issues already. Fridge has been replace 5 times and just went out again yesterday, water pump went bad, already replaced the battery in December and now the battery is bad again. It smells like rotten eggs which tells me it is overcharging. Any clues as to why. I guess I need to pull everything out and find the inverter. I am think I am having buyers regret with this unit. I have another camper that is a 2004 model and have never had any problems or spent as much money keeping the thing up.
