My wife and I have swapped off driving numerous times. We are driving to get somewhere, and then having our fun. Lots of people giving opinions that work for them. Not even taking into consideration what you are asking. I get it. Do what you want. We all know about opinions don't we. We all have them, among other things. Just drive within your abilities. Don't get too tired. We actually enjoy the drive. But that's just US... I'll not suggest you do anything other than what you want to do. Simple as that.
Guess I need to throw in that this was not towing. Just visiting family mainly..
