Just got back from an 1,170 mile "weekend" trip to Virginia Beach with the class c hauling a full size '14 Explorer. Worked great, averaged 7.9 mpg going down and around 7 coming back due to generator running for A/C. This trip was for my son wrestling in the national duals tournament, so the toad was almost mandatory to shuttle from the KOA to the convention center, beach, etc. Next big trip is the end of June to Nashville, not sure we'll take the toad on that one as it shouldn't be needed as much. Either way, it's not a huge difference in driving with or without. With us, it would be a coin flip whether it goes or not, depending on the activities planned on the trip.
