2011 CRV batt dead after towing

We have a 2011 CRV that we tow and have never had an issue before. On the return leg of our last trip, we stopped more than usual for dinner etc so it was an unusually long day. When we got home the battery was dead. All the research I did prior to setting it up to tow told me that I didn't need to hookup a battery disconnect or pull a fuse because our model does not have Nav. I checked prior to towing and nothing was left on (fan, radio, interior lights, etc). So is this a common problem with long days of towing? Should I install a disconnect or pull a fuse from now on? How does that affect the radio and computer etc? I'd rather not get into running a charging cable from the MH, I usually look for less invasive methods. The tow lights are not run through the CRV, they are extra and run directly from the MH so no issue there.

    Even though you don't have Nav you still have power on to the display screen when the key is in the position to tow. On my 2013 I installed the roadmaster disconnect switch that just kills the power for the display screen. Doesn't affect the radio settings. I have not had any issues towing all day with this setup. Very simple to install yourself. I mounted my switch in one of the blank plates on the lower left side of the dash. PM me if you need more info or help with the install.

    Effy, since this is something new that has happened, you are probably due for a new battery. I've already bought a new battery for our 2013 CR-V. The first one lasted exactly 3 yrs.

    Our 2007 had 3 batteries over 5.5 yrs. The first battery was replaced under warranty as it was apparently defective. The second battery lasted 3 yrs.
