I have a 2006 Eddie Bauer Expy with the tow package and a small travel trailer.
I plan on installing a 20 amp DC to DC charger to recharge a 100 ah lithium battery in my travel trailer while driving between campsites. This charger connects directly between the car's battery and the house battery on the trailer.
The vehicle does not have a navigation system, so I am assuming it has the 110 amp alternator. There is a sticker on the alternator that says "A1358F", which I have not been able to cross reference anywhere.
The charger will only be used when towing the trailer. This means that the front and rear AC will also likely be going, the headlights will be on, the dvd player/stereo and phones plugged into cigarette lighters charging via USB adaptors.
While driving, the engine is usually at around 2,500 rpm and will rarely see 3,000 on the occasional hill. It's a very light trailer.
I feel like I should upgrade to a larger amperage alternator, but I understand that using the 130 amp one can cause issues.
Maybe I am mistaken and the total load will be acceptable with the factory 110 alternator.
Any advice would be appreciated.
