I've just bought my first samurai last friday to use in Arizona for desert running. The heater doesn't kick out much heat and last Feb I was in Arizona looking at houses and the water hose to my 5th wheel froze. In my studying of samurais' I've learned that poor heaters are a common problem. As it is with mine. Someone must have solved this problem and I sure could use some help. My wife's idea of roughing it is a chrysler 300c. If I want her to go with me in the samurai this problem has got to be solved for morning driving. Please help!
