Beautiful Ember that is better than new by far! The solar and electronics have been much improved.. There is extra battery capacity; Max solar package--800 watts of solar on the roof... I added an extra solar charge controller so that the solar on the side can be better utililized.. The hitch on the front has been upgraded making it much easier to hook and unhook.. lots of small interior up grades that will come with the trailer... Every thing works as it should ! The trailer has a Victron 3000 watt inverter/charger and two Victron solar charge controlers and 4 Lion energy 105 AH batterys all of which is WiFi accessable... There is antisway that can go with trailer but isn't really needed as trailer pulls wonderfully.. I pull the trailer with a SRW one ton diesel ram so I never use the anti sway ( definitely over kill for this trailer ) ! The mounting points for the two propane cyclinders was moved to allow better use of tongue box storage... I think it pulls so well because it has 8 shocks.. two on each wheel !
