What I've discovered on our inaugural summer 70 day trip is that we can go a bit over 400 miles on my 48 gal factory tank. But I tend to not wait until the needle gets past the 1/2 way mark when I'm in a remote area. On the interstates it's not so much an issue if I'm in areas with high populations.
But what I found is there are vast swaths of this country that area sparsely populated. And I need to make sure I've got a full tank of diesel before heading out.
On this latest leg of our journey, I left with 380 miles of range according to the gauge. We had to traverse a national forest where there'd be no fuel for the next 150 miles. I figure no big deal. I've got plenty of fuel. Well, by the time I went up and down a couple of mountain passes, my fuel was going down quite a bit faster than I anticipated.
I made it to our campsite with 150 mi left of range so I was ok, but there's no fuel outside of this town for quite a distance.
So yeah, I'm going to think long and hard about installing an aux tank next before we head out for our long summer trip next year. We'll be heading up to the southern part of the Yukon and I'm not going to take the chance of not having enough fuel.
I'm not sure I need to do anything more than a gravity fed aux tank though.
