"Protect from freezing" dry van experiences.

I need some expertise from a dry van hauling world...
What are your experiences on not allowing freight to freeze in a dry van when the temps outside drop below 20F? I have a truckload of some hot pepper sauce (like Chalupa or Tobasco) that seems pretty liquid and even though neither the broker nor shipper did mention anything about "protect from freezing" verbally or on the BOL and the product has some salt content and is contained in those little glass bottles, I am still concerned because the temps are to fall below 20 even to 9F on Tuesday night and this thing is to be delivered on Wednesday . I will not shut the truck down and try to deliver earlier...or even look at an option of unloading it at a cross docking warehouse and store it there until delivery (expensive option).
Did some of you had something similar that actually froze despite truck idling. I also would like to know about water, beer or wine hauling when the temp outside are in 20's or below; how likely is it for them to freeze despite the truck moving or idling? Are the blankets thrown on pallet tops making that much difference?
I try to stay clear of these in cold weather but this time I was not quite sure what the commodity was until it was loaded....originally it was described as food.

Also, do brokers or shippers assume liability, if these freeze, as they know quite well that they load it on a regular van to a cold weather area?

 

How many days was the transit... more than 2 days on the truck?

Yeah I am afraid of that too. This means that I need to know beforehand what is likely to freeze and what not while they can load anything. Basically, they choose to save money by loading it not on a reefer and they're off the hook no matter what happens. Should have told them to offload the truck as soon as I saw the BOL. This ####### sauce better not freeze....or perhaps they don't even care.

 

Thanks buddy for keeping my spirits high.

 

Just bought a bottle of Tobasco at a truck stop and fixed it on a catwalk...Let it be my panic gauge. .If it does well all the rest will do too.

It would be nice to have some sort of reference of product freezing points while they're in a dry van when the truck is idling. For example, water, beer, wine. This would show to what cold temps it is safe to haul it.

Well, I'll let know about a Mexican hot sauce after I'm done.
