Got my 2012 Mazda 5 to haul my tadpole trike and other bikes. Now I find nothing fits inside. Height is to short and length just a few inches to short. Everything I've read says don't use any rack that hangs on the tailgate as it won't hold much weight. Considered a trailer hitch and a hitch rack but have been told the weight would be exsessive. As much as I don't want to (too old for all the lifting) I'm considering a roof rack for transport. Any of you haul a trike in or on your 5 and have any recommendations?
