We have a friend (well friend of a friend) that pulls his Nissan Leaf on a trailer (maybe a dolly) behind his moho. He has a Sinewave inverter somehow hooked up to his 12 volt accessory battery. It in turn is fed from the DC to DC converter which gets its power from the main 30 KWH traction battery. Not sure if he has to have it in accessory mode or what but he can go weeks off this setup. Don't think he powers everything in the coach though. I think it is just the fridge. Kinda cool. Not something we plan to do with either of our EV's but its kinda neat. I think the DC to DC converter has some pretty small limitations though. From what I have read on the leaf forum it is around 1400 watts. I can see future EV's with 70 to 100 KWH batteries like the Tesla being really handy for dry campers. Maybe an inverter connected directly to the traction battery thru the fast charge port. Who knows.
