2017 30' AS - Lithium batteries located under rear bed & tongue weight
Hi All,
I am planning my Lithium install with the Lewster in the spring.... planning on 600 amp hours of Victron 'powa' and the batteries and hybrid inverter will be installed in my 2017 30' international under the rear queen bed - see attached picture - Blue shaded area has been designated for batteries + inverter + a few ancillaries.
Based on my back of the envelope math, I am looking at something like:
minus (-) ~92lbs from the battery box (remove stock Interstate Group 24s)
add (+) ~275lbs in the center isle under the rear queen bed (2x 300ah Victron lithiums + 3000VA hybrid inverter)
My tongue weight has been measured at 990lbs on the CAT Scales with weight distribution applied and ready for camping. So static tongue weight is currently sitting at perhaps 1,100 lbs without WD (I'd need to check my CAT scale numbers to be certain). GVWR for the 2017 30' international is 8,800 lbs.
Just curious what others with similar installs (batteries under the rear queen bed on a 30') have measured in terms of overall reduction of tongue weight given the weight shift. I am thinking 150-200lbs when the dust settles, which brings me down to the ~10% of GVWR range when fully loaded and no WD applied.
I currently use an equalizer hitch but will likely make the move to a propride for what it is worth.
Thanks Airforums!
