First rack was made with 2 x 4s and a couple of release skewers for my pickup. It fit between the cab and the wheel wells and set in, lift out. Next had one similar to @noobinsf for the minivan. Also used it on the Stratus. Now using a rack similar to @squirtdad save I use fork mount trays. But really the only time it gets used is if I am hauling the tandem. Got a sidewinder for that. Otherwise the front wheel comes off and the bike goes in the hatch. Got lucky and scored a full wind deflector for the front. Really cuts down on the wind noise. Those little wing things they sell don't work.

@Grand Bois. Any roof rack empty or not cuts into your mileage. But so do rear racks.
