We're trying to get an early start heading out west this year in April. We're going the South route out and North route back so we will experience some freezing snowy weather for sure. A mix of 50/50 ...

To answer your question directly windshield washer fluid is good to -20 degrees and is less than 1/2 the price of RV antifreeze.
That's an incredibly bad idea.
The 'antifreeze' is alcohol because it's designed to EVAPOURATE so as not to form ice on your windshield.
When you pour it into a tank with as much surface area as a grey or black tank, it evapourates very quickly and leaves you with a tank of straight water.
It really depends on how you use it. I open all low point drains and blow out the water lines and use the windshield washer fluid in my traps and toilet. If I go south for the winter I wait until it gets warm enough before filling FW tank. I have never used RV antifreeze and have been winterizing as described for the last 10 years.
I'm not sure how many traps or toilets your unit has, but mine takes maybe a cup per.
If you had two sinks, a toilet and another appliance (washer) with a drain that would take maybe 4 cups.
A half a gallon is too expensive? You need to find something cheaper?
No, the OP asked for a cheaper alternative to freeze-proof his black and grey tanks, 76 gallons in total, not a couple P traps.
Even at a 50/50 dilution rate (which likely still wouldn't be safe) that would be well over $100 per dump, and reduce his tank capacity by half.
