Some advice from my truck driver husband...
He's been running hard since all of this started. There is no shortage of loads for the time being. He's talked to his dispatcher and a couple of brokers. They're saying that his job is safe and he will have plenty of work. With good miles comes a good check.
What he has learned is that brokers and load managers have raised their rates because of the high demand for trucks. It's good for my husband because he makes more money, but it's bad for the consumer because these costs eventually gets to them.
He's been telling his family to only buy what they need. There is no need to hoard or go crazy. Trucks are running and they are doing their jobs. Be patient, he tells me. Food and other items are still in good supply.
He hasn't had many problems other than sometimes there are an excess of trucks at some receivers or shippers. Production appears to have been raised from what he can tell because of all this.
For a long time now, he rarely eats at a truck stop. They are horribly unhealthy and expensive. He's cooked his own food inside his truck and he knows it's relatively healthy and more often than not, better than he can get anywhere else.
The biggest complaint for him is the lack of parking at truck stops and some rest areas.
The takeaway is to shop as you normally would. Don't be excessive and be patient.

He's a great cook so no worries there. He rarely eats out of a can anyway. 
my sleeper is equipped with a 2 burner hot plate, a small microwave and a small refrig/freezer and I cook most of my own meals when possible.
I work in a grocery store. Our distributor has been spotty on deliveries, I think because it's more profitable for them to send extra trucks eastern MA/Boston way than it is to send them to western MA and our small co-ops. All of our small communities are trying to shelter in place. With our children home (in my case a 7 month old and a daughter home from cancelled college) and lots of time... we have been cooking and eating A LOT MORE. And of course needing more toilet paper too because we're ALMOST ALWAYS HOME! I keep about an extra weeks worth of TP in the house usually, but that normal supply is being used every 3 days. It's like the meme that keeps popping up for me saying "Damn, this is the second time this week i've had to replenish my 2-week liquor supply!"
probably the only alcohol sold in liquor stores that might be effective for this.
It seems that people aren't hoarding it the way they are buying up the liquid antibacterial soaps. Bar soap lasts longer and does just as good of a job for washing hands.
I never thought of using liquid chlorine (the pool chemical) but it would be effective but perhaps dangerous for novices to use.
I've been hauling Walmart trailers exclusively from their distribution center just north of Barstow, Ca to the Walmart's in Las Vegas and Pahrump, NV. non stop except to get some sleep and do my 34 hour restarts.
Walmart has been fantastic to us independents during this crises, they let us use their facilities to wash up and use their parking lots to park our trucks and get some sleep and they've been paying top mileage rates.
Tell your husband from one truck driver to another truck driver, Keep On Truckin.
Tell your hubby we wish well for him.
Face, hands, mouth, nose, eyes - don't open the door for an entry point.
Be Well !
Tell your husband thanks for what he's doing on behalf of us.
