I bought a 14' Aluma trailer to carry my Subaru behind my Roadtred Class B van. It has a double axle. In answer to the question about getting into campsites. I generally did not have any problems. I preferred pull throughs for obvious reasons but when confronted with a back in, I would take the car off the trailer and back the trailer and Roadtrek into the spot. It really wasn't too much of a problem. I never saw it as a real hassle. Having the car was nice. I was traveling with two dogs and being able to put them into the car when I wanted some space to myself was nice. I am now looking at trailering or towing a Smart Car. I haven't decided which to do yet but it's nice to know that Aluma has a trailer for me for that car.
