We're on a road trip from Florida to Massachusetts in our 16 ft Scamp
towed by a 4 banger/5 speed Chevy Colorado. Truck is maxed out but is handling things just fine. Averaging between 16 and 20 mpg depending on conditions. Just two of us and our mini-dacshound Molly.
Here's a photo from Tranter's Creek Campground near Washington, North Carolina. Not our favorite place but it ranks a 4 star rating in Woodall's (more like a 2 in my opinion). Yes it has a pool, full hook-ups, wireless internet (not free) but the spaces are in an open field and so close together that our neighbor's sewage hook-up was under our picnic table. On the plus side, we really didn't need to rig our awning
as the motor home next to us provided plenty of shade.
Here's a photo, we get the same amenities as the other guys.
