I’m hoping that Airstream is aware of this thread and is taking notes, as we know Tesla does for some TMC threads. In that spirit, I’d like to offer my eStream wish list; maybe this will come to their attention.
As background information for them, so that it is understood I have some experience towing with an EV, I estimate I have over 15,000 towing miles on my Model X 100D. I tow a
Safari Condo “Alto” F1743 that has been
extensively modified by covering the roof with flexible solar panels that charge two 300Ah LiFePO batteries connected to a 3,000W inverter. The trailer has the Caravan Mover option that uses two electric motors to drive the wheels at about 1.5mph for campsite maneuvering. It does not provide assistance when towing.
Ever since Dethleffs showed their e.home Coco concept trailer a few years ago I’ve wanted a self-powered trailer that would minimize range loss when towing. I could be persuaded to switch to an eStream, and would like to see it include these features;
— approximately 1000W solar panel max output should be possible based on the eStream roof area shown in the videos
— DC charging, at least 120kW charge rate (250kW would be better), CCS compatible
— AC charging up to 11kW with adaptors for NEMA 14-50, TT-30, 5-15 (J1772 not necessary)
— Charge rate adjustable using the eStream app (iOS and Android), also capable of setting up a charging schedule
— A focus on weight reduction. No wood, minimal use of steel in the chassis. Emphasis on lightweight composites and aluminum. Using that approach, a
21 ft Safari Condo A2124 weighs 2,568 lbs dry. The eStream battery packs and motors/inverter likely weigh at least 1,300 lbs. Try to keep the eStream dry weight below 4,300 lbs.
— Heat pump for HVAC, and a quiet unit unlike what Safari Condo uses which is very noisy. Glad to see the eStream concept does not have a big AC unit on the roof!
— eStream app using Bluetooth controls all the trailer lighting (100% LED and all lights dimmable) also controls the HVAC and shows solar panel output, battery charge level, charging rate, charge history, battery DC output, inverter output, also shows fresh/grey/black water tank levels; instead of having multiple different interfaces and screens inside the trailer try to consolidate everything in the app
— 3000W inverter standard
— dual burner induction cooktop standard
— microwave standard
— 12V DC fridge with separate freezer compartment
— Multiple USB A and C charging ports; 2 A + 2 C on the forward wall and 2 A + 2 C on the aft wall.
— AC outlets fore and aft and at kitchen counter, also exterior outlets on each side.
— openable, screened windows fore and aft, double pane acrylic windows for sound/heat insulation
— ventilation fan for main cabin and for bathroom
— wall mounted hand shower head inside, with quick disconnect on the hose so that it can be connected to hot/cold water supply on exterior, on bathroom side, for outside showering
— single hot/cold mixture controls inside and outside (
please no separate hot and cold water controls!)
— spare tire mount below tongue
— storage compartments accessible from the exterior, one on each side
— dedicated exterior storage for up to 20 ft dump hose, I have
one of these by Valterra
— optional wireless rear view camera with in-tow vehicle display screen that can clip to the rear view mirror
— optional dual bike rack on tongue capable of supporting up to 100 lbs total (allows for e-bikes)
— optional router and antenna for user-installed SIM card to create local wifi, I have a
Cradlepoint router and a
Panorama antenna
Thanks for, hopefully, reading this!
Sincerely,
Possible future eStream owner
