73+ burb tank is 41-42 gallon. The large blazer tank is 31 gallons. I installed the 31 gallon tank in my truck and it fits around the hitch just fine. I snagged the frame brackets from a donor truck and reworked them to fit. Worked like a charm. I did reinstall the tank backwards to keep the filler on the drivers side. This also gives some clearence for pulling the diff cover. Using the factory brackets you can also use the factory tank skidplate. The suburban tank is 1-3" bigger in all dimensions.
