Towing MMH four wheels down

Re: Towing MMH four wheels down
I got my base plate installed on my MMH yesterday and towed it about two miles to my house. I put the key in the notch one back from the start position. I noticed that in that position, there is a message in the nav screen that says "System is Off" which I understand the nav/radio etc are off. My concern is I wondering how much electricity is being used by this meassage and will the cranking battery be dead after I've towed the car all day? I would assume this message wouldn't use much electricy, but, anybody got any thoughts on this.
0) Off
1) Acc
2) Run
3) Start
If you keep the Acc on, better make sure everything is turned off. Acc is working off the 12 volt battery and will run it down. If you place the key in the Run position, you working off both batteries and can drain both batteries. My '05 FEH allows me to turn the Acc off in Neutral, but does not go to the full off position (between Acc and Off). This is where I suggest you leave the key when towing. I do not have a message on the dash in this position. It must just break the Acc on position, so there is no power (or little when the door lights come on etc.). I think the 12 volt battery drain would be the same if the key were removed in the Off position, JMHO.

We'll find out. This coming weekend I'm be towing the MMH about 600 miles to New Orleans. I'm glad to hear the engine using the EV batteries to crank the engine. If that is the case, why are there such exact instructions in the owner's manual about jump starting the 12v battery? Why would you need to do this? I'll definitely leave the key in the acc position. I'm waiting to hear back from another rv'er (viewfinder) about this issue. Viewfinder, if you're lurking here, please see my PM at rv.net.

GaryG, how do you know all this stuff (LOL)? I've now learned something else! So even if the 12v. battery runs down, it's a mute point because the EV is going to start the car and then the generator will recharge the 12v battery....right?

Please let me know... I currently have a tow dolly that we used for our 02 Jetta, but I still have my tow bar from our old Geo Tracker. Did you have Camping World do the install or someone else?

Real world report. I have now towed the MMH hybrid for 1300 miles over a period of three days. I towed it with a Blue Ox towbar that I had installed at a local RV dealer. The base plate has serial number 00006 on it so there are, at least, that many units being towed four wheels down. During the three days, I did not start the engine. It started as usual when I arrived in Sarasota. The nav screen had the message on it that I mentioned earlier, but, that didn't seem to run the battery down. Anyway, no problems.
