I've got a 2004 express extended cargo van. thoughts on installing the optional rear fuel tank to use with the standard tank. sure would love to go further on fill ups.

 

That is a lot of extra weight to pack around, so unless you really need the extended range, I would not bother....especially if you already have the 118 litre tank. I get 600 kms hwy on that.

 

I've never heard of an optional rear aux. tank for GM vans, is this a GM option? I know of a few mfg. that make bigger tanks for pick ups, but I've never seen one for a van. I'd love to be able to do something like this for the fleet of vans at work.

 

I was meaning the rear mounted tank that is used on the GM box trucks and class c motor homes.
