We have a ladder bike rack and it works well enough. However, a couple of years ago we left New Hampshire in January when the temp was 33 degrees and it was raining. The highway crews had salted the roads pretty heavily and all of that salt water coated the bikes. By the time we got to Florida, the bikes had rusted anywhere that wasn't painted including chains and brake cables. If we had realized, we might have washed things down with fresh water at an early stop. Something to think about.
