I have a solar charger on my bran new trailer...so this string of emails is really helping me understand...he said it is a trickle charger and the battery has a conditioner..what on earth is that? He also said the solar charger doesnt often charge the battery all the way...and he used two 50 pound generators when he camped...this trailer doesnt even have a cooking area, heat, or air conditioning... so I dont know what he used it for.
