No problems with heat but agree on the bugs. I don't recall the bike rack I have attached, but has large clamps that come down on top of each one, with no moving at all. Bikes do block some of my headlights while driving, but don't drive much at night with trailer or bikes. Best way to keep my eye on the bikes while traveling.
