What braking system were you using on the CRV? What is the brake light on while you were driving because the braking system was not properly adjusted&?
My blue ox braking system on my CRV requires battery voltage to operate the braking system. Some people have run a 12 V charge line from their motorhome to the CRV. My 2004 CRV does not run the battery down unless I do an awful wide of stop and go driving in the auxiliary braking system is activated quite frequently. You can also start and run the CRV at every rest stop did
you stop at and not wait six or eight hours and that would keep the battery charged.
