Our limit for daily driving is about 9 hrs. After that I must unattach my rear from the seat. I do understand your want to get somewhere quicker as we usually only have a week or two at a time to vacation but riding in a vehicle just seems to lose it's luster after 9 hrs. Everyone is different though. If it's a trip you really want to make and both willing to drive it the way you describe, I say go for it! You won't know if it is doeable for you unless you try it. I myself can't rest in a vehicle so I would never make it but you may be different.
