^^^^^^^^^^^^^That could have been me. :) Yep, I spent about 5 minutes doing this, not really all that much work and time. I'm just not interested in mounting fuel lines and solenoids and running power lines under my truck. I could spend a couple hours doing that on a Saturday, or spend 5 minutes a day while traveling doing it my way. Just boils down to choices.
We usually stop at rest stops or parks during the day and I refuel at one of those. The only time the truck sees a fuel station is at the end of the day when we're unhooked and we can fuel pretty much anywhere we want to.
An auxiliary fuel tank is a wonderful thing...no matter how you hook it up.
