You will not lose any electronic setting by removing the correct fuse. Not sure what you mean by battery fuse as in our Suburban it is the ignition fuse per the manual.

Is there another way to handle this so that the radio and other electronics settings won't be lost each time I remove the fuse?
Thanks

Check on your Acadia and see if you have a steering wheel unlock position without have to turn the key to Acc. If you do, then there is no reason to pull any fuses or worry about charging. Many of the new vehicles, mine included, can unlock the wheel before before the Acc. "click" That is where I tow mine and no problems.

We've been towing our 08 Acadia for 2 years now. Pulling the 50 amp fuse is not a big deal and the only thing you loose is the clock setting on the radio. I can reset it in probably less than 30 seconds. We used a BrakeBuddy for a while and never had a problem with it working off the battery. We now have an SMI Air Force One system that requires no juice unless their is a disconnect. The only time I ever had a problem is when I accidently left the key in the run instead of the accessory position. Even with the fuse pulled a bunch of things were on and the battery was dead when we got to our destination.
Our 08 will not unlock the steering as suggested by brobox. That is a good idea if it will work for you.
My 2009 Malibu recommends removing one fuse, ignition sensor, to prevent running down the battery. Since it is not convenient to get to the fuse and remove it I have not done so. So far in one day towing there are no problems. I run a Brake Buddy from the car battery also so the drain from the ignition sensor is surely less than that. I am curious though and may measure the ignition sensor drain. It is continuous and leaving it on overnight in a multi-day tow might add up.
Have towed a Honda CR-V for a number of years without removing a fuse or having supplemental wiring. First, have a premium high amp battery, watch the battery voltage by a cigarette lighter plug in voltage meter, turn off the braking system (SMI)and key at night, and do the required proceedure 3 minute run each morning which keeps the battery up.
I do carry one of those emergency batteries just in case. Have let the engine run in neutral for a while when towing to charge the battery--when I forgot the icebox and left it on draining the battery.
So, no fuse to mess with and the radio keeps the settings.

An important point about fusing both ends. This isn't your typical load circuit with only a single power supply.
I have a charge line as part of the wiring for my US Gear braking system. Their design uses a 20 amp self-resetting circuit breaker on each end. The value, of course, depends on the gauge of the wiring and the ratings of the connectors. So whether you use 20, 30, or 40 amps will depend on your setup details.
I like the idea of the resetting circuit breaker since there could be significant charging current when first plugging in. For example, if the toad battery is low, and you start up the MH, the voltage difference could be enough to want to drive more than 20 amps into the battery. With a fuse, it would be all over. But with the circuit breaker, it will cycle on and off every few seconds, preventing the wire from seriously overheating, but still providing some current to the toad, allowing it to slowly charge. (Or at least, that seems to be the theory.)

My Acadia book says to pull the 50amp Ign fuse. I do it because it says to and the only ting I have to reset is the clock and the volume speed compensation control setting. It takes 20 seconds to do this.

Wonder how you determined there is "no reason", when the factory/ manufacturer of his vehicle recommends he pull the fuse?
