Large is an opinion.  You need to give a capacity.  1000, 2500, 12,000, 30,000 or even more? I will assume you're looking over 10,000 gallons. I would suggest going 18,000 or over.  Much smaller and you'll have to be very low to handle a full semi load.   There seems to be a lot of demand for 12,000 + tanks in that area.  You will probably have to look outside it to find anything.

You might call Shane Sharp at Cactus Tanks in Chandler, OK 405-240-3612.  I don't know anything about him but I've heard others recommend him

Another possibility, again outside your area, is D & K Tanks at Robinson, IL 618-553-7549

Alliance Truck & Tank in Missoula, Montana 800-632-2038 was advertising in LP Gas Magazine.  Another I again know nothing about them
