Oh, I didn’t own or store the trailer. I rented it when I needed it and just had a little hitch rack to take one bike most of the time.
Fair enough.
My point was that my midsize hatchback had the same internal space for taking things around as your SUV, just with less weight and fuel consumption. Unless your kids are larger than adult sized and you have five of them?
I’ve yet to see this bear out. I have a midsize hatchback - a Chevy Volt - which does not have close to the same space. There is an argument to be made for fuel consumption there, though.
