I mean I have 136. Just have to hit any old overpass off ramp, grab the hose and fill er up. Depending on where you’re at you can pee at the same time. 5 min and you’re back on the road, no need to go into town.
I could gravity feed into my main tank if I wanted to but meh.
I’ve gone 1,900 miles between fill-up. Mixed trailering and empty.
