Mid-Size CCSB Truck Fuel Range on 33s

[CaliRadoZR2]

What are Mid Size CCSB Trucks getting for MPG and range on a single tank running 33" A/T or M/T tires? (CCSB: Crew Cab Short Bed)

My Colorado ZR2 gets 16 MPG with a Max range of 320 miles. No options for extended or auxiliary fuel tanks for the CCSB Colorado. (I know range will go down on the trail)

Wanting to see if any Mid Size CCSB has a option of getting over 500 miles range either using extended or auxiliary tanks?

Your MPG falls in the range of almost every one who posted theirs.
Extended range tanks are more of a nitch market. There's only a couple of companies that make them. You almost never see anything for trucks, especially newer ones. The ones I do see are Jeeps and Landcruisers. I know for my Cruiser its a bit over 2k for one.
Odds are it's going to be one off custom.

Gravity feeding gasoline is illegal in most States if not federally.

I put a 17 gallon aluminum auxiliary in the bed of my Gladiator, then using the supplied AN connections rigged a quick detachable 12v fuel pump and home brewed charcoal canister.

I rarely use it (but when I need it , it is handy. Connect up, pump off to the main tank, vapor canister handles evap and expansion/contraction.

Jeep has a 23 gallon tank, pulling our 2500lb trailer it gets 10ish mpg

this one, or one just like it

Similar for me. . . 20 ZR2 Bison V-6 Gas - 33" BFG KM3s - 4:10 re-gear - Trifecta Economy Tune - 6100lbs - Average 65MPH / 17MPG highway. I carry an extra 9 gallons in reserve on backcountry trips, which gives me approximately 225 - 270 miles of range off-road .
