sounds like you dont tow a car. So you could put on a receiver hitch carrier for the gas and the honda genset. Just be cautious that someone dont steal the gen or gas. Problem with running a vehicleout of fuel is the good chance of scoring the injectors which use gas as a lubricant. But in lieu of doing this just plan to refuel every 1/2 tank indication. Putting gas in an enclosure such as the rvs usuaslly have can lead to fumes in the coach and other issues. Outside is the best. If you tow, have a siphon hose available and a small throw away container or just drive to next location and return with gas but you will need to have an 'approved' container to get it.
