I have basically the same machine only 3 ph. It's been about a year and I still can't believe how well it works! Enjoy! Having that wide a jointer is life altering-- though you will develop some upper body strength pushing wide boards through.
Mine (bought used) came with the pork chop guard, and I hate it. It doesn't work very well and it's constantly in the way. Some day it will irritate me enough that I'll spring for the Euro style guard. Really happy to have the powered bed, I wish it had a couple pre-sets so you could drop it down to the bottom and back up again with a single button push.
If the "mobility kit" means the tow bar I think that if I needed to move it a lot I'd opt for an aftermarket solution like Bora. I used the built-in wheels to move it while installing it and found them difficult to engage-- but I haven't had the opportunity to practice.
