Gas tank capacity only 28 gallons, increase it somehow?

We're considering buying a 2008 Expy to replace our 2001 Expy with about 70,000 miles.

Both would be/are 4x4's.

We tow about 4500 pounds a lot, usually around 58 to 62 mph and have been getting about 10.5 mpg at lower altitudes and 11.5 out west at higher elevations.

When I went to the Ford dealer last week, I noticed on the sticker that the tank only holds 28 gallons instead of the 30 gallons for the 2001 Expy.

The smaller 28 gallon tank for the standard length is sort of a deal killer because to fit the Expy into the parking garage where we live at a condo, I need the standard length. The longer one is an accident waiting to happen possibility.

Has anyone else had this issue come up and how did you solve it? Is there an aftermarket tank of some sort to carry extra fuel?

Easy put a 5 gallon jerry can on the trailer tongue and boost fuel capacity to 33 gallons. Off road shops should have these cans and the rack to hold them.

I'm getting 12 - 14 towing our 5000 pound camper at 65mph. 6th gear at 1800 rpm. We commonly tow across the PA mountains several times a year. I'd think you'd get that as well at those lower speeds if you let the transmission do its job. I average about 19mpg over the same terrain without the trailer at ten-over.

I'd order the 3.73 axles based on our Explorer and Expedition towing experiences.

I strongly recommend the HD towing package (about $350 if factory fitted) as you get better engine and transmission cooling plus the complete wiring package. Yeah, the 6000 pound standard max towing capacity is sufficient for our 5000 pound trailer but the extra ton and a half cushion is at least confidence building and there's no fuel hit with it.

I mounted an OBS2 interface transmisson temperature gage. First tow with it won't be for a couple more months though, but knowing trans, coolant, cylinder head temperatures also takes the worry out of towing.

Why should 2 gallons make a difference!?!?! I had a 99 with the 30 gallon tank and I would get about 315-325 a tank. With my 07 and the 28 gallon tank I consistently get 340-360 a tank, who cares about the other 2 gallons. Smaller tank more mileage, don't let 2 gallons change your mind.
