No, experience with sidecars, but seems like it would work ok, not as weather tight as a car however. When we had a C-Class, we towed a small, lightweight Geo Metro (3 cylinder, manuel). Might be lighter than a sidecar & the trailer one might need to tow it. Geos are not made anymore, but it was really a Suzuki...it prove to be tough little ride. Rated at 50 mpg as well.

We have a sidecar rig but never travel with it. Instead we take 2 small motorcycles inside a trailer.
More versatility at least for us. Plus we can carry all we need between 2 of us. Enjoy whatever you do.
I sure wouldn't try it - a sidecar rig is unique in that the sidecar wheel is not located in line with the pusher wheel - they are offset. If you simply lift the front wheel off the ground then the bike will tip to the right. The only safe way to tow a sidecar rig is on a trailer.

I would question that add for long distance, I have heard from many bike mechanics and you cannot tow a bike with this long distance, somthing inside the trans/clutch plates will overheat if the motor is not running, use a trailer for bikes.
