Austin to Terlingua

[ishouldbuyatacotruck_imp]

Hi y'all! I'm planning my first solo trip this fall from Austin to Terlingua. Nothing crazy, just over 1,000 miles round trip. Giving myself plenty of time to get there - I think this will be my route.

Day 1 - Austin to Del Rio
Day 2 - Del Rio to Terlingua
Day 3 - Tooling Around Big Bend
Day 4 - Terlingua to Rocksprings
Day 5 - Rocksprings to Austin



I'm looking through the forum to get recommendations for tank and tail bags, and I'm sure I'll post photos, but if y'all have any tips, I'd welcome them! I'm planning to hit the road in early November.

Some questions:
[ul] [li]What size extra fuel tank should I carry, if at all?[/li] [li]Best headphones?[/li] [li]Are our tires readily available? I'm so worried about a flat.

Thanks y'all!
