Overnight stops (truck stops, etc) with shore power?

That monster 5ver doesn't have onboard power?

Towing that rig around and wanting a lot of quick overnight options, the simple answer is bring your own power.
Also cost effective vs paying for a campsite and you can always recoup most or all of your investment in a generator if you don't want or need it down the road.

And not nearly as limiting. Anywhere you stop the rig for the night, only need to pull a cord to the truck bed and fire up the genny.
