Cab storage is a good idea.
I used a router sled running on extruded aluminum rails to flatten my top. The sled made sense to me because
1. I didn't have hand planes to do the job.
2. I didn't know how to use hand planes at all. The task seemed daunting to me.
3. I had to remove a LOT of stock in some areas following top glue-up.
I borrowed the side rails from work. They were quite flat (I used a straight edge and a taut line to verify flatness). It took a while to make the sled and align the side rails. I then inserted a dial indicator and ran a profile of the top to find the lowest area. The actual routing took a few hours and made a big mess of shavings/sawdust. Eye, ear and respiratory protection mandatory.
Once done routing there are a whole lot of very small grooves that will need to be cleaned up. I used a ROS and 120 grit. They could easily be sanded down with a block of wood. A sharp hand plane could clean them up in minutes.
From your photos the top appears to be in decent shape. Have you laid a straight edge across the top in different areas to check for flatness? If your top is pretty flat then hand planes would make a lot more sense than a router. A wide belt sander would also be easier.
Mike, you will need to have the utmost level of trust in your router collet. If the bit slips it will cause problems.

The sled must be FLAT and support the router with minimal sag. You must guide the router without applying downward force - the weight of the router will do the job. I started with a new bit and it was trash bin material by the time I'd finished.
Here's a pic from my gallery. I was about half way through routing the top. The photo exaggerates the grooves. The grooves clean quickly and easily. If you find a router bit with a very flat top and the axis of the router is perpendicular to the surface then cleanup is a cinch.
