As some one who tows using a tundra and a 7k TT .the biggest issue is the tank. I tow around 150 before I am looking at next gas stop in the next 30 miles.i do carry a gas can or 2 just in case. I am sure you know that. I will not carry too much junk either.
Koa always have drive through and usually have a few full hookup sites for later arrival so you fill a form and just park.
Have fun, I have many 5000 miles motorcycle trips , small Suzuki sport bike with 110 mile range. Be efficient and enjoy.i would follow the same plan if I was doing a trip. Look for the rest area and pullovers on highways so you can gas up fast and grabs a bite and be on ur way.
