Not killer, especially if you've got a second set of hands. Make sure you've got all the single use bolts on hand before starting to rip things apart. Get the flywheel holder tool and an RMS installer if applicable for your seal.
I'd plan on dropping the subframe and pulling the driveshaft...
Medium sized dogs are objectively the best
Small enough they're still easy to handle and can sit on your lap, big enough to still keep up when you're doing outdoorsy stuff and you don't have to totally baby them.
