HRV is FWD and Manual Transmission. Is the difference in towing hrv behind a rv and pulling 3 fuses based on time only? Extended towing (8 hours plus) pull 3 fuses while "normal" towing (less than 8 hours ) fuses can remain in vehicle and operational since hrv ignition must be in accessory mode either way. the fuses are interior fuse block 20A accessory power socket and 7.5 A ACC fuses and in engine compartment 10A Back Up fuse. Am I correct that the reason the fuses must be pulled in extended towing is that the power draw will drain the battery? Is there additional problems if they are not pulled for extended towing?
