I plan to purchase a 2012 crv. I would like to know if anone has used a battery disconnect on this car while towing? I do that now on a 2004 honda element with no problem.
We don't use a battery disconnect, but a 12 v charge line in the light cord between the MH and CRV battery. As per the Honda owners manual, we turn off the radio or navi system and the heater controls. Honda only recommend pulling the accessory 7.5amp fuse for extended towing periods (8hrs or more). Can't say at what point the battery will go dead, we've only towed a couple of hours at a time since getting the new car.

Wouldn't a battery disconnect switch cause your radio settings to erase? As you can see in our Sig, we have an '07 CR-V. We had a fuse disconnect switch run to the fuse that operates the radio/nav. That way, we don't have to reach under the dash to remove that very 'difficult-to-get-to' fuse.
Also wondering, if you disconnect the battery, would your tail lights still work?

We have a 2008 Honda CRV and we have towed it several, several times for 6 to 8hrs straight. One time when we were on the road 10hrs straight (which I will never do again), I did start it up during a lunch break..... I let it run for about 20 minutes.
Before hooking up at the start of a trip, I run it around the block for about 10 minutes. Then I hook up. When I am finished hooking up, I get in the car and turn the radio and everything off, then I run it up through the gears. I leave it in each gear about 30 seconds winding up in neutral (I never put it in reverse). I leave it there and turn the ingition switch all the way to the left (accessory stop) until it stops. The only things that still have power are the clock and the antenna (for my tire pressure system). The car will not lock electroncally with the key in the ignition so we have to lock the car physically with a spare key we have. When we stop overnight, I always put the car in park and remove the key and then lock it up.
In the morning time (before we get on the road), I get in the car, start it up, and let it run for about 20 minutes and then I go through the above procedure again.
Oh!, I almost forgot. Just as we pull out to get on the road, and as a final check, my wife stands outside as I slowly pull forward, just to be sure the tires on the CRV are rolling and not sliding.
So far, we have never had a problem.
We have been doing this since the CRV was new and have never had a problem with the battery.
Just thought I would comment....

STEVEP220,
You don't need a battery disconnect. Even if you purchase the CR-V EX-L with Nav, all that's needed is a charge line from the coach to the CR-Vs battery and, you're set. It will supply enough voltage, and more, to keep your CR-Vs battery up to snuff, even with long tow hours. It's very easy to set one up. Many coaches already have the 12V+ at the trailer plug and, all that's needed is to continue it on through the pig tail and up to the toads battery. A fuse at either end or, if you really feel it's necessary, one each end will protect the complete circuit should anything odd happen. Once it's in place, you're set forever.

Your owner's manual on page 256 tells to pull the 7.5A accessory radio fuse and 7.5A accessory key lock fuse to prevent the battery running down, It also tells you that if you are going to tow for 8 hours in one day, to repeat the "before towing your vehicle procedure" at least every 8 hours (Keeps transmission lubed.) I used the 12V center pin of the RV receptacle to the CRV battery, along with a ground. This eliminates all the fuse pulling or necessity of installing a fuse disconnect switch. If you want to really get serious add a diode and a fuse to the hot wire. Make sure the diode is wired correctly to limit current flow only to the CRV battery.
Just pulled my 2012 CRV on a 250 mile trip. Ran 2 hours the first day. Car started no problem. Ran for 20 minutes and shut off. Started the next morning and ran 6-7 minutes. Towed 3 hours and it would not start. I turned everything off but did not pull any fuses. I made a temporary charge line to use tomorrow for the 5 hour drive home.
